domain of f is also the domain of g and h, since they are defined as multiples of f. since range of f = [2,5], range of g = [3*2,3*5] = [6,15] range of h is [4*2,4*5] = [8,20] range of g is 3*range of f, not 3*domain of f domain is the same for all, since g and h are defined ...

on the second, the domain does not include -1 nor -3, you have to be careful on the non-included points. Same on the range, you can list it as 9-e,1+e where e is epsilion. For an all together , domain: neginf to +inf range: neginf to 9, excluding -1+e to 1 (check that). There ...

An example of a domain is how many gallons of gas are in a car's gas tank (say, 0 to 15 gallons) and the range would be how far that can drive with what is initially in the tank. "Domain" describes the values that an independent variable can have, and "range" is the resulting ...

Division is not allowed by zero. So the domain (for t here) cannot include when t is a root of t^2-5t-66=0 http://www.freemathhelp.com/domain-range.html

Another question about domains and range how would I find the range of (3x-4)/(6x-1) ? Without using a graph the domain is x can't be 1/6 What is the range?

Firstly f(x)=(x=4)(x-2) is wrong you have two = signs. I'm assuming it's a + or another -. a) Well, you know f(x), so -f(x) just has a - in front of it. f(-x) means put -x in everywhere you see x b) f(x), -f(x) and f(-x) are all of the form y = ax^2+bx+c which is a parabola in...

give the domain, range, and zeros of: f(x)=absoulte value of x-3. f(x)=x^2-4x-8 f(x)=(x+1)(x+1)(x+1). f(x)=4 f(x)=-'9x-1)^2+16 y=squareroot x. i don't understand how i konw what the range, domain, and zeros are...please give some answers so i get it

Ok so g ° f = {(1, 4), (2, 2), (3, 2), (4,3)} There are two 1s in the range of f(x) though (1,2) and (3,1). . .Does that mean anything? Is this correct: Does g ° h = {(1, 2), (2?, 2?), (3, 2), (4, 1)}? For this one there was no 2 in the range of h. Also, for h^2 = h ° h, what ...

I posted a problem earlier and made a mistake the question is what is the domain and range of f(x)= log subscript 3 (1-x)? Sorry! The answer is the same. The domain and range will be the same as if it were log base 40.

I will assume you meant f(x) = 3 + e^(4-x) or else you would just have a straight line since e^? can have any real number as an exponent, the domain of the function is any real number for the range ... as x ---> positive large, e^(4-x) becomes very small e.g. e^-100 = 3....

so, f is defined for x > -4 and y < -1. 2*f(x) has same domain, range is y < -2. f(-x) has domain (-x) > -4, so x < 4, range y < -1. 3*f(x+1) + 4 has domain (x+1) > -4, so x > -5, range y < 3*R(f)+4 so y < 1. -2*f(-x+5)+1 has domain (-x+5) > -4...

that is all the values of f(x) for x in the domain of f. For example, y = 3x-4 has domain all reals. Also the range is all reals, since you can find an x for any y chosen. y = x^2-5 has domain all reals, but the range is only [-5,∞) since x^2 is always positive, and -5 ...

The domain of y=f(x) is the range of values of x such that f(x) exists. We know that the ln() function does not admit negative arguments, so the domain of f(x) consist of the ranges of x which makes x^2-4x non-negative, or x^2-4x≥0 .... (1) The solution to equation (1) is ...
