All are negative exponent property except for the top right one
−2(13x−15)
distribute by multiplication -2 to 13x and -15
-26x+30
Inverse is the opposite.
A negative value is an inverse of the same positive value and a positive value is an inverse of the same negative value.
Examples:
-2 is the inverse of 2
5 is the inverse of -5
The answer is:
f(x) = x, g(x) = -x
f(x) = -8x, g(x) = 8x
