Question

Can someone help me here:

Answer 1

when the exponent is 0, as in 2^0, what value is that ? any idea?

Answer 2

I'm not sure what you mean, but do you mean that d because of that the graph it would be rising?

Answer 3

They want you to know that
2^-1= 1/2
2^0 = ?
2^1 = 2
2^2 = 4
2^3 = 8

Have you learned this ?

Answer 4

notice the pattern. to get from 2^3 to 2^2 you divide by 2
example 2^3 is 8. divide by 2: 8/2= 4 , and that is 2^2
if you keep doing that, you can figure out 2^0

Answer 5

yes i have

Answer 6

you should find 2^0 is 1
and try to remember that x^0 (for any number x except x being 0), you get x^0 = 1

now what is -3* 2^0 ?
it is -3*1
in other words, when x is 0, y = -3
the curve goes through the point (0,-3)
which curve does that ?

Answer 7

top right one

Answer 8

the top right shows the curve going through (0,3)
is that what you want ?

Answer 9

oh, yes. top right looks good
