same slope different y-intercept

opposite reciprocal slope flip and switch slope y-intercept can be anything

m = slope multiplied with x b = y-intercept by itself

rate of change constant of variation m

exponential growth function

curves up from left to right b > 1

exponential decay function

curves down from left to right 0 < b < 1

Roots, Zeros, X-intercepts, Solutions

minimum or maximum value of a quadratic

1 any base to the power 0 equals 1

(a^x)(b^x) sharing rule - share the exponent with each factor in the base

(a^x)/(b^x) sharing rule - share the exponent with each factor in the base

y = a(b)^x a = y-intercept initial value b = base growth or decay factor

a line that a graph approaches but never crosses In Algebra 1 it is the x-axis (y = 0)

Linear Parent Function

y = x OR f(x) = x Goes through (0, 0) and (1, 1)

Quadratic Parent Function

y = x^2 OR f(x) = x^2 Goes through (0, 0) and (1, 1)

\ a(c) / \ / factor \ / factor a / \ a / \ / b \

x-method graphing to find the factors

f1(x) = (ac)/x f2(x) = (ac)/x + x Ctrl T, Ctrl 6 Look for b in the 3rd column Factors are in 1st and 2nd column

Transformations add and subtract

Translation Vertical works normally Horizontal works opposite

Transformations multiply by a number

Stretch/Compress Remember hands move... side to side for HORIZONTAL up and down for Vertical

If I have ordered pairs...

I can put them in a table and use List and Spreadsheet
