The function f(x) = 3x – 9 is shifted 2 units up. Which equation correctly describes the new function? A. g(x) = 6x – 9
B. g(x) = 3(x + 2) – 9
C. g(x) = 3x – 7
D. g(x) = 6x – 18

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
