  1. Gary has his function g(x) = 10x and Amy has her function a(m) = 10m . Homework Help ✎

    1. Each person is going to choose a whole number at random from the numbers 1, 2, 3…10, and substitute it into his or her respective function. After they do this, what is the probability that g(x) = a(m)?

    2. Find and simplify an expression for g(x).a(m).

Notice that g(x) and a(m) are equivalent functions, what is the probability that Gary and Amy pick the same number?

Assume Gary has chosen a number. How many chances does Amy have to pick the same number?
Out of how many choices?

Remember the exponent rules.

10x + m
