Answer :
Answer:
[tex]2[/tex]
Step-by-step explanation:
To solve this, you would just substitute 4 in for the x.
[tex]f(x) = 2x^2-30\\f(4) = 2(4)^2-30 = 2*16-30 = 32-30 =2[/tex]
F(x) = 2x^2 - 30
F(4) = 2(4^2) - 30
F(4) = 2(16) - 30
F(4) = 32 - 30
F(4) = 2
F(4) = 2(4^2) - 30
F(4) = 2(16) - 30
F(4) = 32 - 30
F(4) = 2
