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

step-by-step explanation:

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
