If the vertex of a parabola is (8,10) , what is the axis of symmetry?

x = 8

Step-by-step explanation:

The axis of symmetry for graph is always set up as "x="

So, if the x in this ordered pair is 8, then the axis of symmetry is also 8.

(I have posted a picture below as proof...)

i can you with this answer

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
