given the function f(x) = −2x² + 3x + 10, find f(1) and f(3). choose the statement that is true concerning these two values.
the value of f(1) is the same as the value of f(3).
the value of f(1) cannot be compared to the value of f(3).
the value of f(1) is larger than the value of f(3).
the value of f(1) is smaller than the value of f(3).

  The value of f(1) is larger than the value of f(3)

Step-by-step explanation:

Put the numbers in the equation and do the arithmetic.

  f(1) = -2(1²) +3(1) +10 = 11

  f(3) = -2(3²) +3(3) +10 = 1

11 is larger than 1, so f(1) is larger than f(3).

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
