the relation between two sets that associates every element of the first set to exactly one element of the second set.

f(x) = 2x − 3

x2 + 2x +5

fx= 2x^2+3x+4

f(x)=ax³+bx²+cx+d

The polynomial function with degree one

y=mx+b

5x^s-2 +1

The graph of a quadratic function

standard form

a function that involves only non-negative integer powers or only positive integer exponents of a variable in an equation

y − y1 = m(x − x1)

In mathematics, the degree of a polynomial is the highest of the degrees of the polynomial's monomials (individual terms) with a non-zero coefficient

A parabola contains a point

how many roots

a function that can be described by an equation of the form f(x) = ax 2 + bx + c, where a ≠ 0

Hannah's electricity company charges her $0.11 per kWh (kilowatt-hour) of electricity, plus a basic connection charge of $15.00 per month. Write a linear function that models her monthly electricity bill as a function of electricity usage.

A gymnast dismounts the uneven parallel bars. Her height, h, depends on the time, t, that she is in the air as follows:
h = -16t2 + 8t + 8
a) How long will it take the gymnast to reach the ground

If the parabola opens up, the vertex is the lowest point. If the parabola opens down, the vertex is the highest point.

2x3 + 3x2 – 11x – 6 = 0
determine roots

a function of form f(x)=ax³+bx²+cx+d where the coefficients a, b, c, and d are real numbers, and the variable x takes real values, and a ≠ 0.

Three pounds of squid can be purchased at the market for 100 per day plus. Determine the equation and represent the function that defines the cost of squid based on weight.

A gymnast dismounts the uneven parallel bars. Her height, h, depends on the time, t, that she is in the air as follows:
h = -16t2 + 8t + 8
b) When will the gymnast be 8 feet above the ground?

A parabola also contains two points

x3 − 6x2 + 11x – 6 = 0
