The required graph is See the step by step solution

## Step 1. Given information.

The given quadratic function is $f\left(x\right)=-{\left(x-4\right)}^{2}$

## Step 2. Determine the horizontal and vertical shift.

Compare the function with$f\left(x\right)={\left(x-h\right)}^{2}+k$ and $h\mathrm{and}k$.

localid="1646225245025" $f\left(x\right)=-{\left(x-4\right)}^{2}\phantom{\rule{0ex}{0ex}}f\left(x\right)=a{\left(x-h\right)}^{2}+k\phantom{\rule{0ex}{0ex}}So,h=4\phantom{\rule{0ex}{0ex}}k=0\phantom{\rule{0ex}{0ex}}a=-1$

## Step 3. plot the graph  of the parent function.

Plot the graph of $f\left(x\right)={x}^{2}$. ## Step 4. Reflect the graph about x-axis.

Reflect the graph of $f\left(x\right)={x}^{2}$about x-axis to plot $f\left(x\right)=-{x}^{2}$. ## Step 5. Horizontal shift of the graph.

Shift the graph of $f\left(x\right)=-{x}^{2}$ to 4 units right to plot $f\left(x\right)=-{\left(x-4\right)}^{2}$.  ### Want to see more solutions like these?
