Answer:

[tex]m(x)= -7x[/tex]

Step-by-step explanation:

A fuction has an inverse if it passes vertical line test.

[tex]b(x)= x^2+3[/tex] is a horizontal U shaped graph . when we draw a vertical line then it crosses the inverse graph at two points. So it is not a function.

[tex]d(x)= -9[/tex]

Inverse graph is a vertical line that does not pass vertical line test. so it is not a function.

[tex]m(x)= -7x[/tex]

Inverse graph is a graph of a line (linear function). Linear function always passes vertical line test. Inverse is a function

[tex]p(x)= |x|[/tex]

Inverse of absolute funciton does not pass vertical line test, so it is not a function.
