Using the graph of f(x) = log10x below, approximate the value of y in the equation 10y = 3.

i medal and fan thanks

can't open the file!!

OpenStudy (itsmichelle29):

okay

OpenStudy (anonymous):

but the question is "find y if 10y=3" Is it not that y =3/10? or \(10^y=3?\)

OpenStudy (itsmichelle29):

y ≈ 0.48 y ≈ 0.01 y ≈ 1.48 y ≈ −2.01

OpenStudy (itsmichelle29):

so it would be A

Wonder!!! why do we have to use the graph????

OpenStudy (itsmichelle29):

IDK

OpenStudy (itsmichelle29):

is the answer correct???

OpenStudy (anonymous):

oh, I got it. Yes, the answer is correct

OpenStudy (itsmichelle29):

thank you

OpenStudy (anonymous):

The reason is , at x =3, the graph is about 0.48 other options: y =0.01 at 1<x<2 y =1.48 at x > 6 y = -2.01 at x < 1 just y =0.48 is the correct one.
