IM2 WW#1

the point on a graph where the y-value of the function equals zero.

symmetric curved graph of a quadratic function

the direction a graph is facing

should be used when factoring doesn’t work.   

y = a(x-h)^2 + k

a quantity that may change within the context of a mathematical problem. Represented with a letter

polynomial with only one term

polynomial with exactly three terms

two terms that are squared and separated by a subtraction sign

plug in zero for x and solve. 

the point on a graph where the x-value of the function equals zero.

the highest exponent determines the polynomial’s degree.

the other words that mean x-intercept.

the parabola of the quadratic function is concave up and has a minimum.

numbers or variables that are multiplied together to get a larger term.

y = ax^2 + bx + c

a line that divides the graph evenly on both sides. Goes through the vertex.

factor, quadratic formula, or inspection method

     use inverse operations to solve for x.

      a mathematical expression involving the sum of powers in one or more variables multiplied by coefficients

the number in front that is being multiplied by a variable.

the parabola of the quadratic function is concave down and has a maximum.

the number to which another number or variable is raised

the point on a graph where it changes direction.

    polynomial with exactly two terms

located at the vertex. The lowest point that a graph reaches

y = (x + a)(x + b)

located at the vertex. The highest point a graph reaches.

used to record the inputs (x) and the outputs (y) of a function

polynomial where the biggest exponent is 2.
