When a number is raised to a power it is multiplied by itself so the number gets larger. Because the answer is a fraction, this means the power is a negative value.
Find the number 5 has to be raised to be 125 and then make is negative:
5 x 5 x 5 =125
The answer would be a = -3
g(x) = 2x-6
f(x) = -4x +7
(g•f)(x) = g(f(x))
= 2(f(x)) - 6
= 2 ( -4x+7) -6
= -8x + 14 -6
= -8x +8
now
(g•f)(1) = -8(1) + 8= -8+8
= 0
so option a is answer
