What is the range of the function y = x?

Range of x = y : (-∞, +∞)

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

The Definition of a graph's range is the following,

Range: All possible set of outputs a function can have.

Knowing this we can begin to see the possible outputs of the graph. We can say that the input is x and the output is y. Since the output is the same as the input and both are variables, then there are an infinite amount of possibilities. This being the case the range is from negative infinity to positive infinity.

Range of x = y : (-∞, +∞)

I hope this answered your question. If you have any more questions feel free to ask away at

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
