What is the range of the discrete finite function?

Option D

Step-by-step explanation:

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.

In plain English, the definition means:

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

How to find the range

1.The range of a function is the spread of possible y-values (minimum y-value to maximum y-value)

2. 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?)

3. Make sure you look for minimum and maximum values of y.

4. Draw a sketch! In math, it's very true that a picture is worth a thousand words.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

30,40,50 is correct answer
