Answer: 2a+ay+2b+by
Step-by-step explanation:
(a+b)(2+y)
=(a+b)(2+y)
=(a)(2)+(a)(y)+(b)(2)+(b)(y)
=2a+ay+2b+by
=ay+by+2a+2b

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
