calculator matrix

2nd matrix, edit, #’s, 2nd quit, 2nd matrix, (b) rref(), 2nd matrix [a]

Diagonial on matrix

Normal 3 solutions

0000 matrix

Infinite solutions

000#

No solution

In most word problems the third equation should be equal to 0

True

Shade above

> / underlined >

Shade below

<\ underlined <

Absoloute value

2nd window + flip sign of number thats equal to ex. 7\-7 >7/<-7

If the > is underlined and closed the number line dot

Is filled in and use brackets

If the > is not underlined the numberline dot should

Be open and use ()

#(x+#)-#

Front # is stretch/ compression or reflection, x+# is oppisite sign and is left/right, -# is up/down

How do you complete the square

X2+x#+___=#+___ (dont flip sign)

Quadratic formula

Calc for quadratic applications

Stat edit, enter #’s, stat calc 5., alpha trace y1

Even degree end behavior

As x —- -infinity f(x) —— infinity

As x ——- infinity f(x) ——infinity

Odd end behavior

As x ——- -infinity f(x)——- - infinity

As x ——— infinity f(x) ———- infinity

Odd v. Even end behavior

Odd - f(x) is diffrent

Even- f(x) is the same

When looking at equations how do you determine end behavior

Look for the highest exponent value and determine if its odd or even
