Asap , will give to best answer 4. ray needs creating the second part of the coaster. create a unique parabola in the pattern f(x) = ax2 + bx + c. describe the direction of the parabola and determine the y-intercept and zeros.

Answer and step-by-step explanation:

Let a = 4, b = 3 and c = 2.  This gives us

y = 4x² + 3x + 2

This will be a concave up parabola; this is because it is facing upward.

The y-intercept will be the value of c, 2.

To find the zeros, we set the equation equal to 0 and use the quadratic formula:

0 = 4x² + 3x + 2

The quadratic formula is

Using our values for a, b and c,

There will be no real roots (zeros) of this function, since we cannot have the square root of a negative using only real numbers.

good luck!

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
