For all functions of the form f(x) = ax2 + bx + c, which is true when b = 0?
the graph will always have zero x-intercepts.
the function will always have a minimum.
the y-intercept will always be the vertex.
the axis of symmetry will always be positive.

The correct answer is:

The y-intercept will always be the vertex.

Explanation:

The vertex is found by first finding the axis of symmetry, using the formula

x = -b/2a

If b = 0, this gives us

x = 0/2a = 0

This means the point (0, c) will be the vertex.  This is also the y-intercept.

c

i just took the test on e2020

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

answer: i feel you honey.
