Answer:
The value of f(3) = 13
Step-by-step 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(3) = 2 * (3)²/2 + 4
= (2 * 9/2 )+ 4 = 13
Therefore the value of f(3) = 13
13
Given in the question a function
f(x) = [tex]\frac{2x^{2} }{2}+4[/tex]
when we plug in x = 3
[tex]\frac{2(3)^{2} }{2}+4[/tex]
2 in denominator and numerator will cancel out
[tex]3^{2}+4[/tex]
9 + 4
