Using the function concept, it is found that f is a function, as each student is related to only one GPA and only one number of credits.

In a function, <u>one value of the input can be related to only one value of the output</u>.

In this problem:

  • The input is the student.
  • The output is the student GPA, and the number of credits earned.

Each student is related to only one GPA and only one number of credits, hence <u>one value of the input is related to only one value of the output</u>, and f is a function.

Answer:

C) 1

Step-by-step explanation:

Since this a linear table, there has to be a minus or plus. In this case it's +3 or -3. When starting at top, it says 10. Next is 7. The difference is -3. So after is 4. Again, -3. And finally "?" For this you -3 from 4 because it is linear and that is the pattern. The answer is 1. So C is correct

Answer:

a)

p(r)=(r-5)\cdot 1.05

b)

p(15.50)=(15.50-5)\cdot1.05=10.50\cdot1.05=11.025\approx11.03\ \$

Step-by-step explanation:

a)

Assume that r is a regular price before discount and tax

Including discount, we substract 5 from r. We get (r-5).

Then, we include tax by adding 5% value of (r-5)

Including a tax we may realize by multiplying initial value (r-5) by 1.05, where an ending .05 is percentage value of a tax

b)

in a formula p(r)=(r-5)\cdot 1.05 we substitute r=15.50  and calculate the value on the right side of the sign "=".

You solve it too, using a calculator.

If you push the following buttons:

1 5 . 5 0 - 5 = + 5 %

you should get a result 11.025, after approximation to the 2 digits after comma there is 11.03
