Given: f(x) = 3x2+ 1, g(x) = 2x - 3, h(x) = x
g-1(x) =
a. -2x + 3
b. (x + 3)/2
c. 2(x + 3)
f(x) + g(x) =
a. 3x^2 + 2x - 2
b. 5x^3 - 2
c. 3x^2 + 2x + 4
f(-2) =
a. -11
b. 13
c. 37
f(3) + g(4) - 2h(5) =
a. 13
b. 23
c. 33

For this case we have the following functions:

We have to:

is given by:

Thus, the correct option is the option is A.

On the other hand,

Thus, the correct option is the option is A.

We also have:

Thus, the correct option is the option is B.

Last we have:

Thus, the correct option is the option is C.

Option A, A, B, C

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a
