What is the value of f(x)=4x-7 for x=-3

F(x)= -19

Step-by-step explanation:

Just plug in ‘-3’ for every ‘x’ in the equation.

4(-3)-7

-12-7

F(x)= -19

Hey there!!

Given :

... f(x) = 4x - 7

What is f(-3)?

... f(-3) = 4(-3) - 7

... f(-3) = -12 - 7

... f(-3) = -19

Hence, the answer would be "-19"

Hope my answer helps!

I believe the correct answer from the choices listed above is option A. If f(x) = (xm + 9)2,  then f(x) is an even function for all values of m. The reason of that is because no matter what m is, assuming it is an integer 2m will always be an even number. Hope this answers the question. Have a nice day.
