(-3)(7) = -21.  

y^8 and c^3 have different bases (y and c) and thus cannot be merged.

So we end up with -21c^3y^8.

4.b.

Answer:  See below.

Step-by-step explanation:

<h2><u>For the equation f(x) = 2x</u></h2>

3.a.  f(6) means use x = 6 in the equation f(x) = 2x

so f(6) would be f(6)= 2(6)

<u>f(6) = 12</u>

3.b.  f(-11) = 2(-11)

<u>f(-11) = -22</u>

3.c.  f(2.75) = 2(2.75)

<u>f(2.75) = 5.5</u>

3.d.  This is turned around.  We are told f(x)=20, so what would x need to be for f(x) to be 20?  Since f(x) = 2x, we can say 20 = 2x.  Therefore x = 10

f(10) = 20

<u>The rest of (3) are solved in the same fasion.h</u>

<u></u>

<h2><u>For the equation  f(x)= 5x+50</u></h2>

4.a.  f(7) = 5(7)+50

<u>f(7) = 85</u>

4.b. f(-12)

  f(-12) = 5*(-12)+50

<u>f(-12) = -60</u>

<u></u>

Continue in the same fashion for these types of problems.
