Determine the equation of the graph and select the correct answer below. (-1, 3)
Oy=-(x + 1)² + 3
O y=-(x - 1)²+3
Oy=(x + 1)² + 3
O y = (x - 1)2 – 3

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
