At each point (x, y) on a graph of function f, the graph has a slope equal to 4x - 4. If the
graph of f goes through the point (2, 3), then f(x) =
A)
2x² - 4x - 4
B)
2x² - 4x
C)
2x² - 1
D)
2x² - 4x + 3
E)
16x - 12

Answer:

f(x)= 2x² - 4x + 3

Step-by-step explanation:

dy/dx = 4x - 4

y = integrate dy/dx

y = 4x²/2 - 4x + c

y = 2x² - 4x + c

at (2,3)

3 = 2(2)² - 4(2) + c

3 = 8 -8 + c

c = 3

therefore f(x)= y = 2x² - 4x + 3
