Answer:
D. It is U-shaped
Step-by-step explanation:
The standard form of a quadratic function is [tex]y=a*x^{2} +b*x+c[/tex] . The graph of quadratic function opens in the direction of the positive y-axis or negative y-axis, it depends on the coefficient of [tex]x^{2}[/tex] in the function. The shape of the graph of quadratic function is U shaped, because the greatest power of the x in the function is 2.
Hence The shape of quadratic function is U-shaped. It is the characteristics of the quadratic parent function.
