Question

Help please what does y equal​

Answer 1

y=x^2+1

Explanation:

Answer 2

y = 2x^2 +1

Explanation:

This is a parabola so it is in the form

y = a( x-h) ^2 + k

where ( h,k) is the vertex which is at ( 0,1)

y = a (x - 0)^2 + 1

y = ax^2 +1

Pick another point on the graph to determine a

(1,3)

3 = a(1)^2 +1

Subtract 1 from each side

3-1 = a(1)

2 =a

y = 2x^2 +1
