-The graph opes up when a > , and the graph opens down when a < 0.
-The steps to graphing in standard form are to find the axis of symmetry, find and plot the vertex, use the y-intercept to find two or more on the graph, and to finally draw a smooth curve through the points.
-A factorable polynomial with integer coefficients is factored completely when it is written as a product of unfactorable polynomials with integer coefficients.
Roots = answers/solutions
W/ squared binomials will have repeated roots
You use the Zero-Product Property to solve polynomial equations.
-If a variable doesn't have an exponent, their exponent becomes one.
-The coefficient is the number next to the variable
-index is the number in the crack and letter n
-a=radicand
-Bottom goes in the crack(index)
-top is an exponent
-Take the root first then do the exponent
I want listeners to know that using zero and negative exponents evaluate each expression. When an expression has the same base numbers you must add the exponents.
The ones with inequality symbols represent your domain.
Y=mx= b
m=slope
b=y-intercept=4
Substitute m and b into y=mx=b
Identify the endpoint and the x-value
The vertex of the graph f(x)=1x1 is (0,0)
The domain of f(x) = 1x1 is all real numbers.
