Answer:

3.A.) It is a function

Domain = {-3,-2,0,1}

Range = {0,-4,0,-4}

3.B.) It is not a function

Domain = {0,1,1,4,4}

Range = {0,1,-1,2,-2}

Step-by-step explanation:

Coordinates to 3.A. are (-3,0), (-2,-4), (0,0), (1,-4)

The Domain is the set of input values which are the x values.

The Range is the set of output values which are the y values.

Coordinates to 3.B. are (0,0), ( 1,1), (1,-1), (4,2), (4,-2)

3.B. Is not a function because it has more than one of the same inputs (x values).

A Function cannot have more than one of the same input (x values).

Hope this helps.

t is Number of Time Periods

in this problem we have

Sandra

t = 1 year

I= $75

P= $2,500

r= ?

substitute in the formula above

75=2,500 (r(1))

solve for r

r=75/2,500)

r= 0.03

Convert to percentage form

r= 0.03 * 100 = 3%

Ron

t=1 year

I = ?

P= 8,000

r= 0.03

substitute in the formula of interest

I = 8,000(0.03 *1)

I = $240
