A college's tuition of $135 per credit hour increases by 5% each year

Step-by-step explanation:

In the situation of this problem, we have:

- The initial college's tuition per hour is

- Then, we know that the price increases by 5% each year. This means that its value increases by

each year, which is equivalent to

each year

So, after 1 year, the price will be

After 2 year, the price will be

So after n years, the price will be

And by substituting the value of p0, we find the final expression:

where n is the number of years.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743

step-by-step explanation:

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4
