Answer:

Explanation:

A.

The standard form of a quadratic equation is given as;

[tex]y=ax^2+bx+c[/tex]

Given the below quadratic equation;

[tex]x^2+10x+8[/tex]

If we compare the given quadratic equation with the standard form of a quadratic equation, we can see that;

[tex]a=1,b=10,and\text{ c = }8[/tex]

B.

We can tell if the graph of the given equation will open up or down by considering the coefficients of x^2.

If the coefficient of x^2 is greater than zero, then the parabola will open upwards but if the coefficient of x^2 is less than zero, then the parabola will open downwards.

Since the coefficient of x^2 in the given equation is greater than zero, then the parabola will open upwards.

C.

To find t
