Attributes of graphs
what is an increasing interval?
When the graph must be going up from left to right.
name step two when factoring
Take out the greatest common factor
The last step for solving equations
set each factor equal to 0 and solve for 1
What does it mean when multiplying exponents ?
to add the exponets
an/m means in what radical rules?
m√an
Another word minimums and maximums are referred to.
Extrema
What type of functions is being dealt with when factoring?
Quadratic and cubic functions
what is being factored when using factoring to solve equations?
polynomials
power to a power when dealing with exponents means....
to multiply the exponets
(u-3x u-5)5/26
1/u5/2
What are the 3 types of discontinuities
Removable, Jump and Infinite
8x2+48x
8x(x+6)
x2+6x=0
(0,-6)
x10/x2
x8
(1/u x u-8)3/7
u3
Describe and explain a removable discontinuity equation and what the graph will possibly look like
The equation will have a variable in the denominator that will cancel out with something in the numerator, will have a open hole on the graph along the line
1-x2
(1+x)(1-x)
2m2+m=1
(1/2,-1)
x5 multiplied by x4
x9
-5q-4/(-5q4)2
-1/5q12
F(x)=x2-5x+6/x-3 solve for the type of discontinuity
(x-2)(x-3)/(x-3) x-3 or "denominator" cancels out so its removable
2x2-10x2-48x
2x(x-8)(x+3)
5x2-21x+11=7
(1/5, 4)
(2a3b2)(3ab4)3
54a6b14
(3√x2 x 5√x4)-3
x=1/x4
