The following is the graph of the quadratic parent function. T/F?

Step-by-step explanation:

The graph of the parent quadratic has the equation

which has its vertex at the origin. That means that (0, 0) is on the graph. Let's check a few other points. It looks like (1, 1) is also on the graph. If x = 1 and y = 1, fill them both into the equation and see if one side equals the other side.

and that's true. Let's check one more point. It appears that the point (2, 4) is also on the graph. x = 2 and y = 4:

and that is also true. So it is safe to say that this is in fact the parent graph of the quadratic function, y = x-squared.

it costs $20 to interview each person for a survey. find the cost to obtain a +- 3% margin of error.

step-by-step explanation:

copy and paste, put it in google

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.
