1)
a)

Given the above graph, identify the graph of the function (line, parabola, hyperbola, or exponential), and give the domain and range as shown in the graph.

Graph Type This is a parabola

Explanation of why you chose that graph type:

This graph is of the shape of a parabola, which opens up. General form of a parabola which opens up is (x+c)^2 = 4a (y+d) where c, d and a are constants.

Domain (-&#945; , +&#945;)
Range [2, +&#945;)

b)

Given the above graph, identify the graph of the function (line, parabola, hyperbola, or exponential), explain in your works, and why you chose that graph type.

Graph Type Exponential function

Explanation of why you chose that graph type:

It looks like the graph of ex. However, as x reaches - &#945;, y approaches the value of -1. Hence this graph is of the form y = -1 + ex

Domain (-&#945; , +&#945;)

Range [-1 , +&#945;)

c)

Notice the impact of y being undefined at x = 0. The graph gets infinitely close to the y axis (where x=0) but never touches it since y is undefined for an x of 0.

Given the graph above, identify the graph of the function (line, parabola, hyperbola, or exponential), and explain, in your ...
