Step-by-step explanation:
[tex]f(x) = 3x^{2} +1\\f(-2) = 3(-2)^{2} +1 = 12 + 1 =13\\[/tex]
The answer is 13.
Hope that helps!
[tex]f(-2) =13[/tex]
[tex]f(x) = 3x^2+1[/tex], f(-2)
[tex]f(x) = 3x^2+1[/tex]
[tex]f(-2) = 3(-2^2)+1[/tex]
[tex]f(-2) = 3(4)+1[/tex]
[tex]f(-2) = 12+1[/tex]
Hope this helps!
