The function f(x)=lnx is transformed into the equation f(x)=ln(9.2x). Select from the drop-down menus to correctly identify the

d1i1m1o1n [39]

The function f(x)=ln(9.2x) is a horizontal compression of the parent function by a factor of 1/9.2

Step-by-step explanation:

The multiplication of a function by a number compresses or stretches the function vertically while to compress or stretch the function horizontally, the input variable is multiplied with a number.

i.e.

$For\ f(x) => g = f(bx)$

where b is a constant.

Now

If b>0 then the function is compressed horizontally

The given function is:

$f(x) = ln\ x\\Transformed\ to\\f(x) = ln\ (9.2x)$

As the variable in function is multiplied with a number greater than zero, the function will stretch horizontally.

The function f(x)=ln(9.2x) is a horizontal compression of the parent function by a factor of 1/9.2
