How do you find the x and y intercepts for #y = x^2 + 2x - 3#?
x-intercepts are :
Standard Form of a quadratic equation is
We have a quadratic function
x-intercepts is a point on the graph where
Split the middle term to find the factors.
Hence, x-intercepts are
y-intercepts is the point on the graph where
Hence, y-intercept is at
You can verify these solutions by analyzing the quadratic graph:
