Question

Can someone help me workout this problem?

Answer 1

If f is any function with a period of 9, determine the period of each related function.
y=4f((1/3)x)

Answer 2

I'm not sure if the equation is clear, but it is 1/3 times x

Answer 3

HI!!

Answer 4

Hello!!

Answer 5

i would go with
\[\frac{9}{\frac{1}{3}}=9\times 3\]

Answer 6

so the period is 27?

Answer 7

@misty1212

Answer 8

i think so yes

Answer 9

like the period of sine is \(2\pi\) and the period of \[\sin(bx)\] is \[\frac{2\pi}{b}\]

Answer 10

someone helped me with a similar problem but solved it differently
the equation was y=(1/2)f(2x+3)-3
and the answer they gave me was 9x(1/2)=4.5
is this correct?

Answer 11

@misty1212

Answer 12

it is the same

Answer 13

it's the same question just a different equation

Answer 14

in this case \(b=2\) so period is \(\frac{9}{2}\)

Answer 15

Okay thank you so much!
