Select the values for the domain and range of the functions graphed below

The domain of a function is the complete set of possible values of the independent variable.

In plain English, this definition means:

   The domain is the set of all possible x-values which will make the function "work", and will output real y-values.

So for Graph 1 the domain is : (-∞,∞)

domain for graph 2 is : [-1,5]

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.

So range for graph 1 is (-∞,∞)

range for graph 2 is [-1,2]

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls
