Answer:
Just took the test,
1)d, 3
2)a, -13
3) c, y=-2x+6
4) c, f'(a)=8a+2
Step-by-step explanation:
For #3, graph f(x)=-x^2+5. Next graph y=-2x+6. You will see that the added equation touches at exactly the point (1,4). this make it the tangent line equation
5 and 1 half this is the answer my son thought of.
Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
<u>Find the value of x when the ball reaches its maximum height.</u>
<u />
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
The vertex of the parabola is at x = 2, with a maximum height of H(2).
