and u get a point like (0,b)

i think its c

oh, can u use wolf ?

pick a few points for x to get a y-value
plot on a graph.

you will get the y-intercept if u put x=0

u know what that means ?
you get a point where the graph cuts y-axis.

when i put x=o i get y=5 on wolf

so, the y-intercept is (0,5)
which eliminates b,c choices

right ?

i thought it was c 0.0

its A
i just turned it and its a

turned it ?

yea the graph they had on wolf was C but if u turn it its A and its (1,5)

when you put x=1,
u get y= 5 (2)^1 = 10
so the point is (1,10)
which rules out d, if you observe....

the awsner was A, i got a 90%

a is correct :)
you can also plot graphs on google btw. Just type in 5(2)^x and hit enter.
