Step-by-step explanation:
n - a number
a number squared → n²
three more than → ... + 3
<em>three more than a number squared: n² + 3</em>
a. = 12
(4 x 6)/2 = 12
b. = 6
(3 x 7)/2 = 10.5
(3x3)/2 = 4.5
10.5 - 4.5 = 6
9
largest value is 9
smallest value is 0
range= 9-0=9
114 feet
Since the rate per minute is 38 ft per minute. You multiply that by three and get your rate for 3 minutes.
No, the relation is not a function.
Since x = -1 produces y = 9 and y = 4, the relation (–1, 9), (0, –1), (–1, 4), (4, 9) is not a function.
