Answer:

Step-by-step explanation:

Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis. This function $3^x+5$ has been moved up 5 units so its asymptote is at y=5. This means the function never goes below 5 in its y-values.

The x values are not affected and all are in the function. This is the domain. So the domain is (-∞, ∞).

The y values are affected and are y > 5. This is the range and it is written

(5, ∞).

Option B is correct.

I believe what we are looking for is area. If so the formula for area of a rectangle is area equals width times length
A=wl

So:

9*13=117

The area would be 117, the amount of wall space needed is 117.

Hope this helps:)
