Answer:
a. [tex]f(2)=24[/tex]
Step-by-step explanation:
Given function:
[tex]f(x)=3x^2+9x-6[/tex]
To find [tex]f(2)[/tex]
Solution:
In order to find [tex]f(2)[/tex],we need to plugin input=2 i.e. the value of [tex]x=2[/tex] in the function and find the output by evaluating.
Plugging in [tex]x=2[/tex] in the given function.
[tex]f(2)=3(2)^2+9(2)-6[/tex]
Evaluating.
[tex]f(2)=3(4)+18-6[/tex]
[tex]f(2)=12+18-6[/tex]
∴ [tex]f(2)=24[/tex] (Answer)
