Answer: [tex]f(2) = 5[/tex]

Step-by-step explanation:

Given:

[tex]f(x) = 3x^{2}-7[/tex]

To find [tex]f(2)[/tex] , all we need do is to substitute 2 for x in the given function

That is :

[tex]f(2) = 3(2^{2})-7[/tex]

[tex]f(2) = 3(4) - 7[/tex]

[tex]f(2) = 12 - 7[/tex]

[tex]f(2) = 5[/tex]

Therefore :

[tex]f(2) = 5[/tex]
