Find the coordinates of the y-intercept for the graph with equation: y=x2+x−1

(0, - 1 )

Step-by-step explanation:

To find the y- intercept, let x = 0 in the equation

y = 0² + 0 - 1 = 0 + 0 - 1 = - 1 ← y- intercept

with coordinates (0, - 1 )

Step-by-step explanation:

Simplification:

Let's compare this equation with the formula.

Since the y-intercept always lies on the 0 in the x-axis, it's x-coordinate will be 0. The y-intercept basically means the y-axis. Hence, the coordinate is (0,-1)

Hence, the coordinate of the y-intercept is (0,-1).

answer: 1 and 3
