In the function f(x), x is replaced with 3x. f(x)=12sin(x)−4 what effect does this have on the graph of the function? in the function f(x), x is replaced with 3x. f(x)=12sin(x)−4 what effect does this have on the graph of the function?

It is horizontally compress by 3 units

Step-by-step explanation:

We are given function as

When we replace x 3x

we get new function as

Whenever 'a' is multiplied to x-->ax

then it is horizontally compress by 'a' units

So, x--->3x

So,

It is horizontally compress by 3 units

y=mx+

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
