Answer:
The answer is C
Step-by-step explanation:
the rise over run,, Change in y over Change in x
the rise is -6 and the run is 1 (in other words )
Find the range of the function
1 answer:
Answer:
c. (-∞, 10]
Step-by-step explanation:
A function from a set
to a set
is a relation that assigns to each element
in the set
exactly one element
in the set
. The set
is the domain (also called the set of inputs) of the function and the set
contains the range (also called the set of outputs). From the figure below, we can see that this function is a parabola that opens downward and whose vertex is
. Therefore, the range of this function is (-∞, 10]

Answer:
60 °F
Step-by-step explanation:
The function can be put into vertex form:
T(x) = 0.264(x² -18x) +81 . . . . factor the leading coefficient from 1st 2 terms
Now, we add the square of half the x-coefficient inside parentheses and subtract the same quantity outside parentheses.
T(x) = 0.264(x² -18x +81) +81 -0.264·81
T(x) = 0.264(x -9)² +59.616
The low temperature for the day was approximately 59.6 °F, which rounds to 60 °F.
Answer:
so
slope is calculated this way:
let's calculate y init by:
3 = -3×2 + b
b = 9
so equation is:
y=-3x+9
