Question

1.Graph quadratic function is (1,-6), ),(5,30), (-4,39). Find coordinate of extreme and its classificaton (either maximu or minimum.

2. Find maximum area of rectangle inscribed og side :
a. 17cm, 17cm and 86 cm
b 20cm, 29 cm, 21 cm
c. w,w,w

Answer 1

Quadratic function is in the form
y = ax^2 + bx +c
Since you have 3 pairs of coordinates of the function, you can find a, b and c. Probably you can graph the function and find the max/min.

For question 2, what is og?

Answer 2

Callisto : og is of

Answer 3

Is question 2 related to question 1? Or is there any information missed here?
Btw, can you solve 1 now?

Answer 4

callisto : no

Answer 5

Which question is the answer ''no'' for?
As for the second question, it's actually quite weird that it says ''find maximum area of rectangle inscribed of side '' without providing what the rectangle is inscribed in..
