Which statement is true of the function f(x) = -3 squared root x
grigory [225]

Using translation concepts, it is found that the function f(x) = -3\sqrt{x} is the function g(x) = \sqrt{x} reflected over the x-axis and vertically stretched by a factor of 3.

<h3>What is a translation?</h3>

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, from g(x) = \sqrt{3} to f(x) = -3\sqrt{x}, g(x) was multiplied by -3, that is, it was reflected over the x-axis(due to the multiplication by the negative number) and vertically stretched by a factor of 3.
