Is the inverse of f(x)=x^2 is also a function true or false

Solution:

The given statement is False.

Explanation:

We have been given the equation

In order to check whether the inverse is a function or not, we can perform horizontal line test.

Horizontal line test:- If a horizontal line intersects the graph at more than one point then the inverse is not a function. If it intersects at exactly one point then the inverse is a function.

The given equation represents a upward parabola shown in the attached image. The vertex of the parabola is at origin.

Now, we draw a horizontal line and check the number of intersection point of the line and the parabola. We can see that the horizontal line intersects the parabola at two points.

Hence, from horizontal line test, the inverse is a not a function.

Therefore, the given statement is False.

what's the question?

step-by-step explanation:

there is no question.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
