Which of the following functions will not have an axis of symmetry x=-1 when graphed

The correct choice is A.

Step-by-step explanation:

The axis of symmetry of the function is given by

If the axis of symmetry is -1 then the relation between the 'a' and 'b' value for all the function that has an axis of symmetry to be -1, is

A.

We can see that

hence this function does not have an AOS of x=-1

The correct choice is A.

B.

, hence this function has an axis of symmetry of x=-1.

C.

This also has AOS x=-1

D.

AOS is x=-1

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer
