Evaluate each functions for the value specified. f(x)=x2-7x+10;find (a)f(0),(b)f(5),(c)f(-2).
Just plug in the value given for f(x)
into the f(x)
ex.
f(x)= x^2 -7x + 10
for the first one
f(0)= 0^2 - 7(0) + 10
f(0)= 10
do the same with
f(5) and f(-2)
but with the f(-2) don't forget the negative.
f(-2)= (-2)^2 - 7(-2) +10
hope this helps =D
rewrite each equation as a function of x.-3x - 4y - 11
If f (x) - 4x - 3 find the following f (-1)
To evaluate the function f(x) = x^2 - 7x + 10 for the specified values, you simply substitute the values into the function and simplify.
(a) To find f(0), substitute x = 0:
f(0) = (0)^2 - 7(0) + 10
= 0 - 0 + 10
= 10
So, f(0) = 10.
(b) To find f(5), substitute x = 5:
f(5) = (5)^2 - 7(5) + 10
= 25 - 35 + 10
= 0
So, f(5) = 0.
(c) To find f(-2), substitute x = -2:
f(-2) = (-2)^2 - 7(-2) + 10
= 4 + 14 + 10
= 28
So, f(-2) = 28.
Therefore:
(a) f(0) = 10
(b) f(5) = 0
(c) f(-2) = 28
