Question

What is the value of f(x) = 1/2x + 5 when x = 4?

Answer 1

f(x)=7

Explanation:

f(x)= 1/2x+5 ; x=4

f(4)= 1/2(4)+5

f(4)= 2+5

f(x)=7

Hope this helps, because I just did this lesson and I was confused at first, but with practice you will get it!

Answer 2

To find the value of f(x) when x is equal to 4, we need to substitute 4 for x in the function definition f(x) = 1/2x + 5. Doing so gives us:

f(4) = 1/2(4) + 5
= 2 + 5
= 7

Therefore, the value of f(x) when x is equal to 4 is 7.
