The low temperatures on New Year's Day in a city for 5 years are shown below. 2°F, -10°F, 7°F, 4°F, -13°F
Part A
What was the average low temperature on New Year's Day for the 5 years?
A. -2.5°F
C. 0.6°F
B. -2°F
D. 4°F
Part B
If, in the 6th year, the low temperature was 7°F, what was the average low temperature for the 6
years?
A. -0.5°F
C. 0.8°F
B. -0.2°F
D. 1.4°F

Part A - B. -2F

Part B - A. -0.5F

Step-by-step explanation:

Part A. -

2 + -10 + 7 + 4 + -13 = -10

-10 / 5 = -2

Part B. -

-10 + 7 = -3

-3 / 6 = -0.5

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
