The function f(x) = 7x + 1 is transformed to function g through a horizontal compression by a factor of 1/3.What is the equation of function g?

Substitute a numerical value for k into the function equation.

g(x) = (7) kx

The correct question is;

The function f(x) = (7^x) + 1 is transformed to function g through a horizontal compression by a factor of 1/3.What is the equation of function g?

Substitute a numerical value for k into the function equation.

g(x) = 7^(kx)

Value of k = 1/3 if the function is compressed by compression factor of 1/3.

Step-by-step explanation:

In transformations, the horizontal stretch or compression for a function f(x) is given by  g = f(bx) where:

b is a constant.

If b > 0, then the graph of function is compressed.

Now, from the question, we are told that the function is transformed by a compression factor of 1/3.

Function is;f(x) = (7^x) + 1

In transforming to g = f(bx), we have;

g = (7^(x/3)) + 1

Since, we want to find k from the format g = 7^(kx)

Comparing with g = (7^(x/3)) + 1, we cans see that ; k = 1/3
