Final

Question 1

a and b in exponential functions…

Answer 1

a cannot be 0, b cannot be 1

Question 2

a and b in logarithmic functions…

Answer 2

a cannot be 0, b cannot be negative

Question 3

when solving logs, remember…

Answer 3

to check for extraneous solutions!
any negatives or zero.

Question 4

coordinates of point p

Answer 4

(cosr, sinr)

Question 5

what does the AROC of a polar function tell us?

Answer 5

the rate at which the radius is changing per radian

Question 6

inverse variation

Answer 6

If x is inversely proportional to y…
y=k/x
k is a constant of proportionality

Question 7

logs are inverses if…

Answer 7

log(b)b or if
b^log(b)

Question 8

linear model for a semi-log plot

Answer 8

given the exponential model y=ab^x, the linear model for the semi-log plot is y=logbx+loga
– the base of the logs is the base of the axis

Question 9

to find c

Answer 9

1. see translation from origin
   2.b(max(x value)+c)=regular max x value
   –cos: 0
   –sin: pi/2
