Substitute (-4, 3) into the equation of curve
3 = 16a - 4b - 13
4a - b = 4
b = 4 - 4a ---- (1)
dy/dx = 2ax + b
At (-4, 3), dy/dx = 0
-8a + b = 0
b = 8a ---- (2)
Fom (1) and (2),
4 - 4a = 8a
4 = 12a
a = 1/3
b = 8/3.
<span>-3 = x^2 + 4x + 1
Add 3 to both sides.
0 = x^2 + 4x + 4
Switch sides.
x^2 + 4x + 4 = 0
For the quadratic formula, a = 1, b = 4, c = 4
discriminant = b^2 - 4ac = 4^2 - 4(1)(4) = 16 - 16 = 0
When the discriminant equals zero, there is a single real solution.
Answer: There is a single, real solution.</span>
