Q
8 Graphing steps
A
1-domain 2-intercepts 3-symmetry 4-asymptotes 5-intervals of increase and decrease 6-local max and mins 7-concavity and inflection 8-sketch
2
Q
how to find x intercepts
A
set =0, solve for x
3
Q
how to find y intercepts
A
plug in 0
4
Q
how to find vertical asymptote
A
denom =0, cant cross out
5
Q
how to find horizontal asymptote
A
find limit as x goes to +or - infinity
6
Q
first derivative test
A
critical numbers, inc/dec
7
Q
second derivative test
A
concavity, inflection points. f’‘(x)>0 is con up, f’‘x<0 is con down
8
Q
how to find critical numbers
A
first derivative = 0
9
Q
even test
A
f(-x)=f(x)
10
Q
odd test
A
f(-x) = -f(x)
