You can use photo math and calculate each equation separately and it shows you the graphs, then pick the answer where the graph looks the same to the question.
hope this helped
Its kinda blurry and I can't read the whole question
Step-by-step explanation:
y = a(b^x)
a = initial value
If b > 0 and b < 1, then 1 - b is the decay factor.
If b > 1, then b is the growth factor.
what function has a growth factor of 3
Function 3
what function has an initial value of 2
Function 2
what function has an initial value of 0.2
Function 4 since 1/5 = 0.2
what function has an initial value of 1
Function 3
what function has a decay factor of 0.2
None. In Function 2, the decay factor is 1 - 1/5 = 0.8, not 0.2.
what functions are increasing across real numbers?
Functions 3, 4
what functions are decreasing across all real numbers?
Functions 1, 2
