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]
