9514 1404 393

Answer:

  c.  Both m(x) and p(x) have the same output value at x = 7.

Step-by-step explanation:

For input value x, m(x) is the output value.

m(7) is the output value of the function m(x) when x=7.

p(7) is the output value of the function p(x) when x=7.

The statement m(x) = p(x) for x=7 is a statement that the output values are the same at x=7.
