5+8=13
-2x-2 = 4
13 to the fourth power = 13x13x13x13 =28561
28561 is your answer
Answer:

Step-by-step explanation:
Exponential functions are represented in the form
, where a is the initial value and b is the multiplier.
Here, we see that when x = 0, y = 4. This means that 4 is our initial value, or a. You can look at the a variable almost being like the y-intercept of a graph.
Next, we must solve for b. We can do 16 ÷ 4 to find the slope, or multiplier of this function, because 16 is 1 input x-value up from 0. 16 ÷ 4 = 4.
So, we now have all the needed variables, so we plug them into the formula

Answer:
y = 2/5x - 5
Step-by-step explanation:
y = 2/5x - 5
(If you go to desmos.com you can graph any equation. It really helps. I'm doing similar things in class, I use it all the time.)
