Using the scenario below, identify the independent and dependent variables. Be sure to include evidence and reasoning to support your claim

A student uses a ping pong ball, a golf ball, and a tennis ball to determine the height of bounce when dropped from a height of 3 meters?

Dependent Variable: Height of bounce

Independent Variable: Type of ball

Step-by-step explanation:

Dependent variable is what is being tested while the independent variable is what changes in the experiment or what causes the dependent variable results to change.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables
