A conical lid's height is 2 centimeters less than the radius, x, of its base. x+
= 0 can be used to find that the radius of lid's base is
If the lid is made of 2511 cubic centimeters of clay, the equation x +
centimeters.

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.
