Question

Which function is graphed on the right?

Answer 1

the answer is C on edge 2020

the answer to the next question is

Sketch the graph of y=7x

Reflect the graph across the y-axis to show the function y=7^-x

Stretch the graph vertically by a factor of 3 to show the function y=3x7^-x

Shift the graph up 2 units to show the function y=3x7^-x +2

Step-by-step explanation:

Answer 2

Answer:
`y=2^(x-2)+3`

Explanation:

To find the equation from a graphed function, you can substitute points into each equation to find the original:

A point on the graph is (2, 4). Substituting this into each equation, we get:

`4=2^(2+3) -2`, which claims that 4 is equal to 30, which is incorrect.

`4=2^(2-3) +2`, which claims that 4 is equal to 3/2, which is incorrect.

`4=2^(2-2)+3`, which claims that 4 is equal to 4, which is correct.

We can test the third function further by taking another point on the graph, (3, 5), and substituting it into the function:

`5=2^(3-2) +3`, which claims that 5 is equal to 5, which is correct.
