Question

Estimate graphically the local maximum and local minimum of f(x) = 4x2 + 3x + 2

Local maximum: (-0.4,1.44); local minimum: (0,-0.37)

Local maximum: (-0.4,1.44); no local minimum

No local maximum; local minimum: (-0.4,1.44)

No local maximum; local minimum: (0,-0.37)

Answer 1

\[ f(x) = 4x^2 + 3x + 2 \] a parabola that opens up, so no max but a min at the vertex

Answer 2

use x=-b/(2a) to figure out your vertex value

Answer 3

when i did ut i got c

Answer 4

vertex at \(x=-\frac{b}{2a}=-\frac{3}{8}\)

Answer 5

The functionfunction A set of ordered pairs where each first element is paired with one and only one second element and no element in either pair is without a partner. is neither even nor odd

Answer 6

!!so D is correct

Answer 7

idrk this oneee but take a guess :)

Answer 8

no i think it might be C
it is usually C

Answer 9

@satellite73 okkkk

Answer 10

A plot of\[4 x^2+3 x+2 \] where x ranges from -0.6 through -.02 is attached.
The calculus indicates that (-0.375,1.4375) is the local minimum.

Answer 11

Thank you for the medal.
