#1.

a.

f(x)=x^3+3x^2+5

f'(x)=3x^2+6x

f''(x)=6x+6

#2.

a. (1-2x)^5=1-10x+40x^2-80x^3+80x^4-32x^5

#4.

5^x=17

xln(5)=ln(17)

Divide ln(17) by ln(5)

Thus

x=ln(17)/ln(5)

#5.

b. f(x)=x^3+4x^2+x-6=(x-1)(x+2)(x+3)

c. f(x)=x^3+4x^2+x-6=(x-1)(x+2)(x+3)

Hence

x=1

x=-2

x=-3

This worksheet is a piece of cake. Hopefully this will get you started.
