Polynomial Functions

100

What is the degree of the function f(x)=5x^2+9x^4-4x?

degree = 4

200

Function g(x) is defined as g(x)=15x^2+4x-11. Does the graph of g(x) open up or down

Up! Because the leading coefficient, 15, is positive 

300

Function h(x) is defined as h(x) = 15x^2 + 4x - 11.

What is the y-intercept of the function?

y = -11 OR (0, -11)

400

You are given the quadratic function f(x)=-2x^2+8x+40. Find the axis of symmetry using the equation x = -b/2a 

x = 2

500

Factor by Grouping: x^2 + 5x + 3x + 6

x(x+5)+3(x+2)

Rational Functions

100

Is this an example of a rational function? y = 4x^2 + x

No, rational functions must have a variable in the denominator

200

Find the horizontal asymptote of the equation f(x)=(5x-2)/(10x+2)

y = 5/10 or y = 1/2

300

Find the vertical asymptote of the function f(x)=(5x-4)/(4x+8)

(Assume there are no holes)

4x+8=0

4x=-8

x=-2

400

Find the coordinates of the hole of the function: f(x)=(x-3)/[(x-3)(x+2)]

(3, 1/5)

500

What is an example of something from your own life that would have an asymptote if it was graphed? 

Ex. Your temperature after being really really cold would have a horizontal asymptote of 98 degrees (you approach that temp as time passes)
