Answer:

D.) y = 2^x

Explanation:

It wouldn't be a negative because then the line would be in the negative area of the graph, below. It wouldn't be 1/2 because the starting line would be on the right of the graph instead of the right.

Answer: D) y = 2ˣ

Explanation:

This is the graph of an exponential function.

The y-intercept is 1 so the first coordinate to try is (0, 1).

Which of the options provided works for that coordinate? all of them

The next coordinate is (1, 2).

Which of the options provided works for that coordinate? y = 2ˣ


A)\  y=-(1)/(2)^x\quad \rightarrow \quad 2=-(1)/(2)^1\quad \text{is False}\\\\\\B)\  y=(1)/(2)^x\quad \rightarrow \quad 2=(1)/(2)^1\quad \text{is False}\\\\\\C)\  y=-2^x\quad \rightarrow \quad 2=-2^1\quad \text{is False}\\\\\\D)\  y=2^x\quad \rightarrow \quad 2=2^1\quad \text{is TRUE!}
