Step-by-step explanation:
By using Implicit Differentiation,
d/dx (y² + xy - x²) = d/dx (11x)
d/dx (y²) + d/dx (xy) - d/dx (x²) = 11
2y * dy/dx + x * dy/dx + y - 2x = 11
dy/dx (2y + x) = 11 + 2x - y
dy/dx = (11 + 2x - y) / (2y + x).
At the point (2, 3), we have x = 2, y = 3.
=> dy/dx = (11 + 2(2) - (3)) / (2(3) + (2))
= 12 / 8 = 1.5.
P.S. Your question is weird because (2,3) is not on the graph, let me know what is the correct question thanks!
Answer:
D
Step-by-step explanation:
Z is the only relation that does not pass the vertical line test, so Z is not a function.
Answer: D
Answer:
The polynomial would be x^4 - 5x^3 + 4x^2
Step-by-step explanation:
In order to find this, we need to take each answer and set it equal to x. Then we solve until it equals 0.
x = 4
x - 4 = 0
x = 1
x - 1 = 0
x = 0
x = 0
Now we have 4 of them and we simply multiply them all together.
(x)(x)(x - 1)(x - 4)
(x)(x)(x^2 - 5x + 4)
(x)(x^3 - 5x^2 + 4x)
x^4 - 5x^3 + 4x^2
