The graph of the function, f(x) = x2 - 5x - 7 opens (up/down) and has a (min/max) value.

see explanation

Step-by-step explanation:

given a quadratic in standard form : y = ax² + bx + c : a ≠ 0

Consider the coefficient of the x² term

• If a > 0 then vertex is a minimum and graph opens up

• If a < 0 then vertex is a maximum and graph opens down

f(x) = x² - 5x - 7 is in standard form

with a = 1, b = - 5 and c = - 7

Since a > 0 then vertex is a minimum and graph opens up

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.
