Part 1: AJ reflected the graph over x-axis.

Part 2: The two x-values are (0,-5) and (-1,-2) . AJ plotted the graph using the function $f(x)=(x+2)^{2}-1$ . This resulted the graph to reflect over x-axis.

Step-by-step explanation:

Part 1: AJ mistakenly plotted over x-axis, which means he reflected the graph over x-axis.The x-value remains the same. Only the y-values are transformed into its opposite sign.

Part 2:

Step 1: Plotting any two values for the function $f(x)=-(x+2)^{2}-1$

Substituting x=0, we get,

$\begin{aligned}y &=f(0)=-(0+2)^{2}-1 \\&=-(2)^{2}-1 \\&=-4-1=-5 \\y &=-5\end{aligned}$

Substituting x=-1, we get,

$\begin{aligned}y &=f(-1)=-(-1+2)^{2}-1 \\&=-(1)^{2}-1 \\&=-1-1=-2 \\y &=-2\end{aligned}$

The two x-values for AJ’s function is (0,-5) and (-1,-2)

Step 2:

AJ plotted the graph using the function $f(x)=(x+2)^{2}-1$ . This resulted the graph to reflect over x-axis.

Aj graphs the function f(x) = -(x +2)^2 - 1 picture shown below.

part 1: what mistake did aj make in the graph?

part 2: evaluate any two x-values (between -5 and 5) into aj's function. show your work. how does your work prove that aj made a mistake in the graph?
