Question

What is the range of the given function?

{(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}

A {x | x = –5, –4, –2, 0, 2}
B {y | y = –9, –3, 0, 5, 7}
C {x | x = –9, –5, –4, –3, –2, 0, 2, 5, 7}
D {y | y = –9, –5, –4, –3, –2, 0, 2, 5, 7}

• What is the range of the given function?
• (–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)

• A {x | x = –5, –4, –2, 0, 2}
• B {y | y = –9, –3, 0, 5, 7}
• C {x | x = –9,–5,–4,–3,–2,0,2,5,7}
• D {y | y = –9,–5,–4,–3,–2,0,2,5,7}

### What is range of a function?

• The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

### The definition means:

• The range is the resulting y-values we get after substituting all the possible x-values.

### How to find the range?

• The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)Substitute different x-values into the expression for y to see what is happening. (Ask yourself: Is y always positive? Always negative? Or maybe not equal to certain values?)Make sure you look for minimum and maximum values of y.
