Question 0

What do we use to determine whether or not a graph is a function?

Answer 0

The Vertical Line Test

Question 1

If two variables, p and q are inversely proportional then the product of the two never change. Which equation shows this?

Answer 1

p*q=k, where k is constant

Question 2

What do we use to determine if the graph’s inverse a function?

Answer 2

The Horizontal Line Test

Question 3

Quadratic Formula?

Answer 3

x= -b(plus or minus) the square root of b^2 -4ac / 2a

Question 4

Discriminant and its Conditions

Answer 4

If b squared - 4ac = 0 then roots are real and equal

If b squared - 4ac > 0 then roots are real and unequal

If b squared - 4ac < 0 then roots are imaginary and unequal

Question 5

Equation for the sum of the roots of a quadratic?

Equation for the product of the roots of a quadratic?

Answer 5

Sum = -b/a
Product = c/a
