Question

Tell whether the table represents an exponential function. If so write a rule for the function X -1 0 1 2 3 Y 1 4 7 10 13

Answer 1

Ok, so

We got the next table:

First of all we're going to check if this represents an exponential function.

The table seems to be a linear function. It's not exponential. That's because if you see, the way that the values are changing is at a constant rate.

In x, we got one to one, and in y, three to three between each value.
