Step-by-step explanation:
Exponential function is given by general form 
Where a and b are constants.
say a=1 and b=2 then we can write function as :

or 
To graph this or any exponential function, we just need to find some points then join them by a curved line.
Like plug x=0, 1, 2,... into above function and find points:
plug x=1

Hence point is (1,2)
Find more points similarly then graph them to get the graph as shown below:
Answer:
The constant of proportionality is 5/3
Step-by-step explanation:
3 * k = 5
k = 5/3
Check
9 * k = 15
9 * 5/3 = 15
3*5 = 15
15 =15
The constant of proportionality is 5/3
Answer:
1.542425 or 4
Step-by-step explanation:
Answer:
55
Step-by-step explanation:
There are 11 tens in 110, so 11 times 5 is 55.
if you want to solve it without a graph you're going to need to use the cubic formula, I'm unsure how else to solve it
