Chapter 2: Q. 27 (page 69)

Determine whether the equation defines y as a function of x.

y=x2

Short Answer

Expert verified

The given equation is a function.

Step by step solution

01

Step 1. Given information

In the given question we have to determine whether the equation defines y as a function of x.

y=x2

02

Step 2. The given equation is y=x2

The equation tells us to take an input xand find their square.

For any input x, these operations yield only one output y.

03

Step 3. For example,

If x=1, then y=(1)2=1.

If x=3, then y=(3)2=9.

For this reason, the equation is a function.
