This is the standard form of a quadratic function, represented as 'y = ax² + bx + c.'
the standard form.
This is a method used to find the exact solution for a system of two equations by adding or subtracting them to eliminate one variable.
elimination method
According to the Product Rule, when multiplying x^3 by x^4, you do this to the exponents to get x^7
what is add them
A line passes through the point (2, 4) and has a slope of 3. What is the equation of the line in slope-intercept form?
y=3x-2
This term refers to the set of all possible output values, or (y)-values, of a function.
range
A rocket is launched from a 20-yard-high platform with an upward velocity of 40 yd/s. If its height h(t) in yards at time T seconds is h(t)=-16t^2+40t+20, when does it reach maximum height and what is that height?
In this "method" of solving systems, you solve one equation for (x) or (y) and "plug" it into the other equation.
substitution
Any non-zero number raised to this power, such as 5^0 , results in a value of 1
What is ZERO
A line is represented by the equation y equals negative 2x plus 7. What is the x-intercept of this line?
(7,2)
The domain must be all real numbers greater than or equal to this number, because you can't take the square root of a negative.
zero
If a quadratic function is written as f(x) = a(x - h)^2 + k, these two letters represent the coordinates of the parabola's vertex.
(h) and (k)
A farm has only chickens and cows. If there are 20 heads and 50 feet, this is the total number of cows.
5
this is the simplified, positve-exponent from of the expression x^-5
What is 1/x^5
Solve 3(x - 3) = 6(x + 5).
x=-13
The domain must be all real numbers greater than or equal to this number, because you can't take the square root of a negative.

A rectangular photo is 4 cm longer than it is wide and has an area of 45 cm^2; these are its length and width.
9 cm and 5 cm?
A vendor sells 35 hot dogs and 52 sodas for a total of $78.50. If the total number of items sold was 87, this is the cost of a single hot dog if sodas are $0.50 each.
$1.50
To simplify (4x6)1/2, you must take the square root of 4 and do the is to the exponent 6
What is 2 multiplied by 1/2
A rental car company charges a flat fee of $50 plus $0.20 per mile. If the total cost of a rental was $130, how many miles were driven?
400 miles.
This is the range of the parent quadratic function f(x) = x2
[0,/ infy)
A train travels 240 km at a constant speed; if its speed is increased by 20 km/hr, the trip takes 1 hour less. This was the train's original speed
60 km/hr?
If you graph two equations and they represent the same line, the system is described by this two-word term, meaning there are an unlimited number of solutions.
infinitely many (or infinite solutions)
