Answer:

13

Explanation:

Given in the question a function

f(x) =
(2x^(2) )/(2)+4

when we plug in x = 3


(2(3)^(2) )/(2)+4

2 in denominator and numerator will cancel out


3^(2)+4

9 + 4

13

Answer:

The value of f(3) = 13

Explanation:

It is given that a function f(x),

f(x) = 2x²/2 + 4

To find the value f(3)

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
