77. The yearly cost of tuition (in-state) and required fees for
zlopas [31]

Answer:

a. \$3107

b. 17 years

c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

Step-by-step explanation:

a.

f(x)=64x+2083

Here, x is a the number of years after 2000 and f(x) is the total cost.

To approximate the yearly cost of  attending a two-year college in the year 2016,  find f(16).

f(16)=64(16)+2083\\\\=1024+2083\\\\=\$3107

b.

To predict in what year the yearly  cost of tuition and required fees will exceed $3200, solve f(x)=3200

64x+2083=3200\\\\64x=3200-2083\\\\=1117\\x=\frac{1117}{64}\\\\ =17.45

So,

x is approximately equal to 17 years.

c.

The present year is 2020.

To approximate the yearly cost of  attending a two-year college in the present year, find f(20)

f(20)=64(20)+2083\\\\=1280+2083\\\\=\$3363

The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.

Find f(-5) if f(x) = 5x + 11.<br> A) 4<br> B) 5<br> C) 6
Andru [333]

Step-by-step explanation: Since f(x) = 5x + 11, we find f(-5)

by substituting a -5 in for the x in the function to get f(-5) = 5(-5) + 11.

Now just simplify the right side to get -25 + 11 or -14.

So f(-5) = -14.
