Evaluate each funtion for the given input values:
for f(x)=4x-3,find f(x)when x=3
so is it f(x)=4(3)-3
f(x)=12-3
f(x)=9? is this right?
Yes!
ok thanks, i have one more question
Evaluate each function or the given input values:
for g(x)=x^3-x, find g(x) when x=(-3)
g(x)=(-3)^3
g(x)=(-27)? is this right?
correction it it should be g(x)=(-30)is this right?
Almost -27 - (-3) = -24
x(x-32)=0
Yes, you are absolutely correct!
To evaluate the function f(x) = 4x - 3 when x = 3, you substitute the value of x into the function.
So, f(3) = 4(3) - 3.
Then, you simplify using the order of operations (parentheses, exponents, multiplication and division, addition and subtraction) to get:
f(3) = 12 - 3.
Finally, you solve the subtraction to get the final result:
f(3) = 9.
So, the value of f(x) when x = 3 is indeed 9. Well done!
