200

Identify the global maximum in format

Global max of 4 at x=3

300

Write an interval notation for the graph below

(-infinity,6]

400

Increasing and decreasing intervals for the graph

Inc:(-2,-1) u (3,infinity)

Dec:(1,3)

500

Removable Dis: x=3

Evaluating Functions

100

f(x)=5x-4 find f(-2)

5(-2)-4=-14

200

f(x)=3x-5

f(-1)=3(-1)-5=-3-5

f(-1)=-8

300

find f(x) if x=5

f(5)=-5-10=15

400

f(x)=6x²+ax-7

f(2)=6(2)²+a(2)-7

=6(4)+2a-7

=24+2a-7

f(2)=17+2a

500

if f(x)=-3x-8 find (5)

f(5)-3x5-8=15-8=-23

f(5)=-23
