See graph and explanations.

Work Step by Step

Step 1. Given $f(x)=2x^2(x-2)^2$, test symmetry $f(-x)=2(-x)^2(-x-2)^2=2x^2(x+2)^2$, no symmetry. Step 2. The leading term is $2x^4$ and we can find its end behavior as rise to the left and rise to the right. Step 3. The zeros are $x=0$ (multiplicity 2, graph touches the x-axis and turns around) and $x=2$ (multiplicity 2, graph touches the x-axis and turns around) Step 4. The y-intercept can be found as $f(0)=0$ Step 5. Use test points as necessary, graph the function as shown in the figure.
