Exam 2 Review

2.1-2.2

100

True/False

The graph of f(x)=a(x-h)²+k, is symmetric with respect to the vertical line x=k.

False x=h

200

Write y=4x²-8x+9 in standard form and graph

SF: y=4(x-1)²+5

300

Draw the graph of 

y=x²(x²-9)(7x+4)³

jeopardy doesn't like me so I can't put the graph on here but I can check your graph or draw it:)

400

Graph

f(x)=x³+3x²+6x+8

The graph should have a zero at -2, yint at 8 and end behavior down-up

2.3-2.4

100

True/False

The possible rational zeros of f(x)=9x³+9x²+x+1 are 1,-1,3,-3,9, and -9

False

200

Find the domain of the rational function

f(x)= (x-1)/(x²+x-6)

(-infinity,-3) U (-3,2) U (2, infinity)

300

Use synthetic division to find the quotient and remainder of 5x³+18x²-4x+1 divided by x-(1/5)

5x²+19x-(1/5)

R: 24/25

400

Draw the graph

f(x)=(x²-x-2)/(x-4)

I'll check your graph or draw it bc jeopardy doesn't like graphs

3.1-3.2

100

Write the exponential in logarithmic form

a⁴+1=7

log_a6=4

200

Compute interest for $3,000 invested at 7% over 9 years compounded daily

$5632.49

300

Graph f(x) = 2-e^-x

I'll draw it

400

Graph 

f(x) =5+log₂(7-x)

I'll draw it

3.3-3.4

100

log₂4+log₅5

(log4/log2)+(log5/log5)

200

Solve for x

(log2x)²=4log2x

1/2,5000

300

Write in condensed form

(1/5)(log₈z+2log₈y)

log(⁵root(zy²))

400

Solve for x, write exact answer using natural logarithms

10^2x+3=13

(ln13-3ln10)/2ln10
