Answer:

Step-by-step explanation:

First, start out with the parent function:

$y = b^{x}$

Now, we look at the transformations, and make the equation.

We see that the graph shifted down 4 units, since the graph's horizontal asymptote is at y = -4.

$y = b^{x} - 4$

We see point (0, -3) to point (1, -1). The value of b would be 3. The reason is that when you plug 0 in, you get 1, then 1 - 4 equals 3. (0, -3),

Then, when you plug in 1, you get 3, then 3 - 4 equals -1. This matches up with the graph.

This is the answer:

$y = 3^{x}-4$

Ethan planted a tree that is 37.5 inches tall.if the tree grows 3 inches each year, how long will it take for the tree to reach

Mila [183]

First find out how many more inches it needs to grow, 54-37.5; It needs to grow 16.5 more inches. If it grows 3 inches a year then you have to do 16.5/3; 5.5. It will take 5.5 or 5 1/2 more years to grow to 54 inches.
