The low temperature for the morning is -3.9°F. If the temperature rises to 24°F in the afternoon, what is the change in temperature?

i think it is c, not positive though

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

see attached

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
