Look at the graph of this system of equations: y = - x2 + 1 and y = x2. at which approximate points are the two equations equal? there more than one answer.

.7, 0.5)
b.(0.5, 0.7)
c.(0.7, 0.5)
.5, 0.7)

option A and C, (-0.7, 0.5) and (0.7, 0.5)

Step-by-step explanation:

The two equations are equal means, the points at which the  two graphs meet.

In that case the x and y coordinates satisfy both the graphs.

let the coordinates at the intersection point be (a,b).

Inserting in first equation,

Inserting in second equation,

Inserting value of b from second to first equation, we get

Now inserting the value of b second equation, we get

Thus points are, (-0.7, 0.5) and (0.7, 0.5)

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
