Question

PLEASE HELP WILL FAN AND MEDAL



below is the graph of f(x)=3log(base10)x how would you describe the graph of g(x)=9log(base10)x?

Ag(x) compresses f(x) by a factor of 3
B g(x) shifts f(x) up 3 units
C g(x) shifts f(x) to the right 3 units
D g(x) stretches f(x)vertically by a factor of 3

Answer 1

No shifting.

Answer 2

Answer 3

we can write this:
\[g(x)=9\log _{10}x=3(3\log _{10}x)=3f(x)\]
so, in order to draw the graph of g(x), it is necessary multiply by 3 the y-coordinate of all points of the graph of f(x)

Answer 4

so D.

Answer 5

D.
