Please help me solve these are quadratic equations: I​

Step-by-step explanation:

a. a, b, c

Quadratic equations in standard form are written as:

The exponents are listed from greatest to least. The quadratic is already in this form, so match up the variables and values in the equation.

b. Y-intercept

The y-intercept for a quadratic is c.

You can also substitute 0 in for x, because the y-intercept occurs when the quadratic crosses the y-axis (at x=0).

We know that c=2, so the y-intercept is c.

c. Maximum/minimum

The entire quadratic is positive, so the quadratic opens up and has a minimum.
