Exercise 1 Page 431

We are given an expression and asked to evaluate it for some given values. x=-2, 0, 2 This means that we should substitute -2, 0, and 2 for x in the given expression and then evaluate. Let's start with -2.

10^(x+1)

Substitute

x= -2

10^(-2+1)

Now, we will do the same thing for the second value.

10^(x+1)

Substitute

x= 0

10^(0+1)
