Am I right? @phi

Or @anyone xD

OpenStudy (anonymous):

4x = 2x? as in x=0?

OpenStudy (anonymous):

I just says that lol, now that I think about it with other thoughts, I don't think its A?

OpenStudy (anonymous):

I wonder if it meant to say 4y = 2x? as it sits, it reduces to 2=1

OpenStudy (anonymous):

xD it would be much more simple that way ._.

ganeshie8 (ganeshie8):

the graphs must represent exponential functions : \(4^x = 2^x\)

OpenStudy (anonymous):

The top says "The graphs of four exponential functions are shown below" but you guys can clearly see that

OpenStudy (anonymous):

Yea, ofc :p

ganeshie8 (ganeshie8):

if so, then use this :- every exponential parent function cuts the y-axis at \(1\)

ganeshie8 (ganeshie8):

so you may simply pick the curves that cut the y-axis at \(1\)

OpenStudy (anonymous):

So C and D .. are you sure lol ?

ganeshie8 (ganeshie8):

you need to be sure, not meh

ganeshie8 (ganeshie8):

\(4^x\) put x = 0, wat do u get ?

OpenStudy (anonymous):

ô.ô I'm not ;~; thats why I'm asking

ganeshie8 (ganeshie8):

to be sure, you need to knw why every exponential parent function cuts the y-axis at \(1\)

OpenStudy (anonymous):

could you explain at little bit further please

ganeshie8 (ganeshie8):

sure :)

OpenStudy (anonymous):

:>

OpenStudy (anonymous):

OHHH WAIT. 4^0 = 1 and 2^0 = 1 Is that why? Because the x represent 0?

ganeshie8 (ganeshie8):

exponential parent function : \(y = a^x\) A graph cuts y-axis, when its x-coordinate = 0. so, lets plug \(x=0\) above and see wat we get for y-coordinate \(y = a^0 = 1\) thus, every exponential parent function cuts the y-axis at \(1\).

ganeshie8 (ganeshie8):

yess, i see you got it !

OpenStudy (anonymous):

Ermagod :D

OpenStudy (anonymous):

I'd give you a cookie :*

ganeshie8 (ganeshie8):

aww ty ty :))

OpenStudy (anonymous):

ohh and this one? >.>

OpenStudy (anonymous):

Sowwie >.<

ganeshie8 (ganeshie8):

Correct ! I'll give u a cookie this time :D

OpenStudy (anonymous):

Ohh staph it you
