Question

Help graphs

Answer 1

the only advice i can give you is to plug in 0 and then 2 for x to find y and you should have two points that can help you determine whihc graph

Answer 2

@reemii

Answer 3

if x=2, y = 1 + 0 = 1.
with this information, what are the only possible graphs?

Answer 4

D :s

Answer 5

D is a good one.
B is also a good one because (2,1) is on the graph.

now, one way to find which one is good is to find another point on the graph.
Another way to find the right graph is to see if the function is increasing or decreasing.

Answer 6

ahh A :p

Answer 7

A isn't good. it's B or D..

Answer 8

oh okay, well hmm D

Answer 9

why?

Answer 10

is the function increasing or decreasing?

Answer 11

decreasing

Answer 12

An increasing function (cubic root) of an increasing function (x-2) gives an increasing function.
dividing by 2 or adding 1 doesn't change that property. The function is increasing.
B is increasing, D is decreasing.
the answer is B.

Answer 13

ah ok :s can you help me with one more

Answer 14

start by determining one point on the graph of the function.
this will filter out several graphs.

explain what point you use and which graphs are the candidates.
