Question 111902: Help! I am not familiar with a TI 83. I need to give four ordered pairs for this, y = 7^x
I had x values of -15, 0, 15, and 30.
The y values that showed up I did not understand, it said 2E-13, 1, 4.7E12, and 2.3E25 Why does it have E?

You can put this solution on YOUR website!
you're raising 7 to the power of x, so you might want to pick more reasonable x values

the E is shorthand for scientific notation ___ En is the same as X 10^n

1200 = 1.2 X 10^3 = 1.2E3
