Graphing Square Root and Cube Root Functions
Instructions: Ensure that all graphs are properly labeled.
1.
When graphing a square root function of the form [math]f(x) = a sqrt(bx + c) +d[/math], where [math]a,b,c,d in RR[/math], there is always either a minimum or maximum value (but not both).
- True
- False
2.
When graphing a cube root function of the form [math]f(x) = a root[3](x+b) + c[/math], where [math]a,b,c in RR[/math], the range is all real numbers.
- True
- False
3.
When graphing a square root function of the form [math]f(x) = a sqrt(bx+c) + d[/math], where [math]a,b,c,d in RR[/math], there will never be any part of the graph to the left of the y-axis.
- True
- False
4.
Given the function [math]f(x) = a root[3](x+b)+c[/math], where [math]a>0[/math], and where [math]b,c in RR[/math] which of the following is true of the graph of [math]f(x) ?[/math] There may be more than one correct answer.
- It is always increasing.
- It has a y-intercept.
- It has an x-intercept.
- The domain is all real numbers.
5.
Graph the square root function [math]f(x) = 2sqrt(x) + 1[/math].

6.
Graph the function [math]f(x) = -3sqrt(x - 2)[/math].

7.
Graph: [math]y=3sqrt(-(x-2))-5[/math].

8.
Graph the function [math]f(x) = 2root[3](x) - 4[/math].

9.
Graph the function [math]f(x) = -root[3](2x)[/math].

10.
Graph [math]f(x) = 1/2 root[3](-(x+1))[/math].
