Question

What function equation is represented by the graph?

Answer 1

Answer:

The correct option would be D, f(x)=2^x-3

Step-by-step explanation:

You can immediatly cross out options A and B because it cannot be negative. If it was negative, the graph would be going the opposite direction, it would curve closer to the negative numbers that the positive. We can cross out C because if it was -2, then it would cross the y-axis at -1 rather than -2.

hope this helps :)
