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.

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
