A.R.O.C FOR POLYNOMIAL

The function is - (with degree-) since the-difference in the Y value(y=-j are constant over equal X value(x=-)

The function has an inverse

At least two inputs aren’t map to the same output y=-

Is when F changes from increasing to decreasing

Local máximum

The highest y value a function reaches

Global maximum

A.R.O.C FORMULA

Y/X= y2-y1/x2-x1

INTERPRET A.R.O.C

ON AVERAGE FOR EVERY - THERE IS A INCREASING/DECREASING OF-

POINT SLOPE FORMULA

Y=m(x-x1)+y1

If a graph is concave up then

Then the graph is positive

WHERE IS CHANGES FROM A NEGATIVE TO A POSITIVE OR POSITIVE TO A NEGATIVE

ZEROS , X INTERCEPTS OR ROOTS

Domain

Is where the graph is read From Left to right

IS WHEN F CHANGES FROM DECREASING TO INCREASE

LOCAL MINIMUM

The lowest y value a function reach

Global minimum

The function does NOT have an inverse

At least two input are mapped to the same output y=-

If the graph is concave down

Then the graph is going negative

Range

Is where the graph is red from bottom to top

Is where the concave is switching

At the point of infection
