Question

Two quadratic functions are shown.

Function 1:
f(x) = 2x2 − 8x + 1

Function 2:

x g(x)
−2 2
−1 −3
0 2
1 17


Which function has the least minimum value and what are its coordinates?
Function 1 has the least minimum value and its coordinates are (0, 1).
Function 1 has the least minimum value and its coordinates are (2, −7).
Function 2 has the least minimum value and its coordinates are (0, 2).
Function 2 has the least minimum value and its coordinates are (−1, −3).

Answer 1

I don't think that it is C, and if it was function 2, i think it would be D.

Answer 2

I forgot how to plug in the numbers to test function one.

Answer 3

\[y= 5x^2+10x+2\] for the second equation. Try graphing it. :D

Answer 4

Ok.

Answer 5

ultimately they (your teacher) just wanted you to find the equation of the second parabola and then see what both minimums were.

Answer 6

-2, -3 is the coordinate that was the lowest.

Answer 7

When I graphed it :)

Answer 8

Answer 9

okay give me just a sec
