(3,8)
Step-by-step explanation:
THIS IS AN EXAMPLE FOR ANY PROBLEM!!
Get the equation in the form y = ax2 + bx + c.
Calculate -b / 2a. This is the x-coordinate of the vertex.
To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
- Good luck!
<span>3. subtract 3
that's the next step</span>
F(x) - g(x) = 9x^3 + 2x^2 - 5x + 4 - ( 5x^3 - 7x +4)
f(x) - g(x) = 9x^3 + 2x^2 - 5x + 4 - 5x^3 + 7x - 4
f(x) - g(x) = 4x^3 + 2x^2 + 2x
f(x) - g(x) = 2x(2x^2 +x +1)
