Please help!! i need to have this assignment done in 45 mins, thanks for the help :D

f(3) > g(3)

Step-by-step explanation:

add 3 into each equation.

f(x) = 4x^4                    g(x) = 10 * 2^x

=                                   =

f(3) = 4(3)^4                  g(3) = 10 * 2³

Solve each equation.

f(3) = 4(3)^4                   g(3) = 10 * 2^3

=                                     =

f(3) = 12^4                      g(3) = 20^3

=                                     =

f(3) = 20,736                  g(3) = 8,000

f(3) is greater than g(3)

f(3) > g(3)

Hope I helped.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
