.Given: F(x) = 3x2+ 1, G(x) = 2x - 3, H(x) = x

inna [77]

For this case we have the following functions:

$F (x) = 3x ^ 2 +1\\G (x) = 2x-3\\H (x) = x$

We have to:

$G (x) * - 1$ is given by:

$(2x-3) * - 1 = -2x +3$

Thus, the correct option is the option is A.

On the other hand,

$F (x) +G (x) = 3x ^ 2 +1 +(2x - 3) = 3x ^ 2+ 1+ 2x-3 = 3x ^ 2 +2x-2$

Thus, the correct option is the option is A.

We also have:

$F (-2) = 3 (-2) ^ 2+ 1 = 3 (4)+ 1 = 12+ 1 = 13$

Thus, the correct option is the option is B.

Last we have:

$F (3)+G (4) -2H (5) = (3 (3) ^ 2+ 1)+ (2 (4) -3) -2 (5) = (3 (9)+ 1) - (8-3) 10 = 28+ 5-10 = 33$

Thus, the correct option is the option is C.

ANswer:

Option A, A, B, C
