For which function is f(x) equal to f-1(x)? a. f(x)=x+6/x-6 b. f(x)=x+2/x-2 c. f(x)=x+1/x-1 d. f(x)=x+5/x-5

A reflection in the x-axis means the y-coordinate will be negated (the opposite sign). This means that g(x)=-f(x)=-(x^2+5=-x^2-5.

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9

the equation is not included but the answer is (1.50, 2.00, 2.75)
