The equation ŷ=−5.9x^2+39x+2.2 approximates the average number of cars that pass through an intersection x hours after 3: 00 p. m.

what is the best estimate for the average number of cars that pass through the intersection at 4: 30 p. m.?

43

47

58

66

im not sure

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
