Answer:

45000000000

Step-by-step explanation:

when multiplying exponents, you multiply base numbers with no exponent (9 and five in this case) and numbers with exponents (10 in this case). 9 X 5 is 45 and 10 to the power of 7 times 10 to the power of 2 is 10 to the power of 9 or 1000000000. 45 X 1000000000 is 45000000000.

Given: f(x) = 3x + 2 and g(x) = 2x - 4
likoan [24]

In f(x) = 3x + 2, the x is being represented in the function. So, if we replace the x with the g(x) functions, we get:

f(g(x)) = 3(2x - 4) + 2

f(g(x)) = 6x - 12 + 2

f(g(x)) = 6x - 10
