Question

what is the equation of the graph

Answer 1

x-h means we move right of the origin by h

that tells me its either 2 or 4

Answer 2

in other words, since we are to the right of the origin by 1.5; then we have to have an x-1.5 in the eq

Answer 3

and we appear to be up from the origin; so we prolly want a + tag on the end; so im gonna guess at 4

Answer 4

i believe most of your problem is that you are playing on a mac computer :)

Answer 5

hey amistre64, is it ok to try like this?
Put x=0 in the four equations, and see for which a real value equal to 2 or 4 comes out. Because the graph has a real y-intercept.

Answer 6

i see 3 might be an option, i couldnt see the innards clearly

Answer 7

you can, but since we are playing in tan i think trying to solve might be harder in general

Answer 8

i think 3 is out since we get a tan pi/2 at x=0

Answer 9

lol, now i know im looking at the way to hard

Answer 10

oh sorry i meant it doesn't intersect x=1.5. so x=1.5 should give an unreal solution.

Answer 11

So the answer is 4, I guess?

Answer 12

right, so at x=0 #3 is bad; so im back to my #4 gut chk to begin with :)

Answer 13

The period is 2 so it has to be either 2 or 4 and it certainly can't be 2 so it is 4.
