I just can help u with

D: all real numbers

R: [3,infinity)

y -intercept :(0,4)

max.: none

min.: (1,3)

The simple interest formula is

i = p*r*t

where

i = interest earned

p = principal (amount deposited)

r = interest rate in decimal form

t = time in years

In this case,

i = 1200

p = 5000

r = unknown

t = 4

so,

i = p*r*t

1200 = 5000*r*4

1200 = 5000*4*r

1200 = 20000*r

1200/20000 = r

0.06 = r

r = 0.06

Convert 0.06 to percent form by moving the decimal point over to the right two spots

so we go from 0.06 to 6.0% which is simply 6%
