Answer:
The value of f(3) = 13
Step-by-step explanation:
It is given that a function f(x),
f(x) = 2x²/2 + 4
<u>To find the value f(3)</u>
For that we have to substitute 3 instead of x
f(x) = 2x²/2 + 4
f(3) = 2 * (3)²/2 + 4
= (2 * 9/2 )+ 4 = 13
Therefore the value of f(3) = 13
You set them both equal to 180 and solve for x so your answer will be 140
