Question

The function f(x)=logx is transformed into the equation f(x)=4.3logx.

Is this Vertical compression or vertical stretch?

Answer 1

that would be vertical sketch

Answer 2

The function
`f(x)=\log x` is transformed into the equation
`f(x)=4.3\log x` is vertically stretch.

Explanation:

Given : The function
`f(x)=\log x` is transformed into the equation
`f(x)=4.3\log x`

To find : Is this Vertical compression or vertical stretch?

Solution :

It is vertically stretch.

f(x) to
`a f(x)`

`0<|a|<1` when a is compressed.

`|a|>1` when a is stretched.

Here,
`a=4.3 >1`

So, the function
`f(x)=\log x` is transformed into the equation
`f(x)=4.3\log x` is vertically stretch.
