functions and graphs

(a)   functions are graphs

 $f\left(x\right)=x^2-2x+\frac{1}{4}x^3$  is  _________________

• a polynomial

• a linear function

• a power function

• a quartic

 Determine whether this function is odd, even or neither.$f\left(x\right)=\cos\left(x\right)$  

• odd function

• even function

• neither even nor odd function

 $t\left(x\right)=\ln\left(x\right).$  What is  $t^{-1}\left(x\right)$  ?

(a)  

What type of function is shown in the figure?

• linear function

• polynomial function

• reciprocal function

• quadratic function

FInd an expression for a cubic function g if g(1) = 6 and g(-1) = g(0) = g(2) = 0

• $g\left(x\right)=2x^3-2x^2+3x+1$

• $g\left(x\right)=-5x^3+4x^2-1$

• $g\left(x\right)=-x^3-3x^2+5x$

• $g\left(x\right)=-3x^3+3x^2+6x$

Find f(-1)


(a)  

A function is a rule that assigns to each value in the domain to (a)   element in the range

• This graph fails the vertical line test

• For a point (x, y) on the graph, (x, -y) is also a point on the graph

• This graph is symmetric about the origin, the x-axis and the y-axis

• This graph is a function
