What do you need to find in order to graph a quadratic?

Step-by-step explanation:

The graph of any quadratic function f(x)=ax2+bx+c, where a, b, and c are real numbers and a≠0, is called a parabola.

When graphing a parabola always find the vertex and the y-intercept. ...

Use the leading coefficient, a, to determine if a parabola opens upward or downward.

it should be a and d. lmk if i'm wrong xd

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
