Question

PLEASE HELP The graph of function g is a vertical stretch of the graph of function f ​​by a factor of 10.

Which equation describes function g?


​​ g(x)=f(10x)

​​ g(x)=f(x/10)

​ ​ g(x)=1/10f(x)

g(x)=10f(x)

Answer 1

Vertical stretch:

Suppose, we are given any function f(x)

and it is asked to vertically stretch graph of f(x) by 'a' units

Vertical stretch means stretching y-value

and f(x) is y-value

so, we multiply 'a' to f(x)

so, our function will become

`g(x)=a* f(x)`

now, we are given

The graph of function g(x) is a vertical stretch of the graph of function f(x) by a factor of 10.

It means that parent function is f(x)

and new function becomes g(x)

and it is stretching vertically by 10 units

so, we can write as

`g(x)=10f(x)`............Answer
