In two or more complete sentences, compare the number of x-intercepts in the graph of f(x) =x2 to the number of x-
intercepts in the graph of g(x) = x2 +2. be sure to include the transformations that occurred between the parent functio
f(x) and its image g(x).

The function f(x) intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.

Step-by-step explanation:

In this question you first form the table for values of x with corresponding values of f(x) that you will use to graph the function f(x)=x².Then do the same for the function g(x)=x²+2.Take a point from the parent function f(x) and compare it with its image in the function g(x) to identify the transformation that occurred.Graph the two equations to visually see the x-intercepts in both equations.

In the parent function f(x)=x² form a table as shown below;

x                      f(x)=x²          coordinate to plot

-3                     -3²=9                (-3,9)

-2                      -2²=4                (-2,4)

-1                        -1²=1                 (-1,1)

0                         0²=0               (0,0)

1                           1²=1                 (1,1)

2                          2²=4               (2,4)

3                           3²=9               (3,9)

Use the coordinates to plot the graph of f(x)=x² on a graph tool and see the number of x-intercept values

In the function g(x)=x²+2 also form your table for values of g(x) with corresponding values of x

x                              g(x)=x²+2                                          coordinate to plot

-3                          -3²+2=9+2=11                                          (-3,11)

-2                          -2²+2=4+2=6                                          (-2,6)

-1                           -1²+2=1+2=3                                             (-1,3)

0                            0²+2=2                                                    (0,2)

1                             1²+2=1+2=3                                              (1,3)

2                            2²+2=4+2=6                                             (2,6)

3                            3²+2=9+2=11                                             (3,11)

Use the coordinates to plot the graph of g(x)=x²+2  on a graph tool to determine the number of x intercept values

You can determine the transformation that occurred too, how?

Take a point on the parent function f(x) and compare it with its image in the function g(x)

Let take point (-3,9) and compare it to (-3,11).You notice x coordinate did not change but the y coordinate shifted 2 units upwards along the y-axis.To determine this dilation you subtract the coordinates of object point from that of image point.

The dilation was (0,2)

Solution

From the graphs, the function f(x), intercepts the x-axis at (0,0), thus it touches the x-axis once.The graph of the function g(x) does not intercept the x-axis at all.
