Question

Please help!! Will Fan and Medal! c:




1. Consider x2 + 4x – 5 = y.
a) What are the roots of the equation?
b) Find the Vertex.
c) Write the equation of the axis of symmetry.
d) Name the y-intercept.

Answer 1

y = x^2 + 4x - 5
y = (x + 5) (x - 1)

Let y = 0.

(x + 5) (x - 1) = 0
x + 5 = 0
x = -5

x - 1 = 0
x = 1

So, (1, -5) will be the answer.
