The temperature at a state park for one day in June can be approximated by the function T(x) = 0.264x2 - 4.752x + 81 0 ≤ x ≤ 18

Lilit [14]

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
