Question

Medal And Fan for helping me understand how to solve it


Two quadratic functions are shown.

Function 1:
f(x) = 4x2 + 8x + 1 Function 2:

x g(x)
−2 2
−1 0
0 2
1 8


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

Answer 1

Least minimum value is where its y value is least

Answer 2

in (x,y)

Answer 3

I don't understand

Answer 4

would it be c because the minimum value of function 2 is lowest at point (-1,0)???

Answer 5

one approach
find the value of x when f(x) = 0
when g(x) = 0 x = -1 f(-1) = 4(-1)^2 + 8(-1) + 1 =
when dy/dx = 0 it gives the max or min use this value in f(x) to give the value

Answer 6

triciaal
I do not think this is a calculus problem.

Answer 7

It is more like Algebra 2

Answer 8

which value of y is the least in the multiple choice? y is inside (x,y)
