Answer: From my knowledge it was Non proportional but get some other answers to be sure!
.(2x-1)
Answer:
18x² - 6x
Step-by-step explanation:
Differentiate using the product rule, that is
y = f(x)g(x), then
= f(x)g'(x) + g(x)f'(x)
here
f(x) = 3x² ⇒ f'(x) = 6x
g(x) = 2x - 1 ⇒ g'(x) = 2, thus
(3x²(2x - 1)
= 3x² × 2 + 6x(2x - 1)
= 6x² + 12x² - 6x
= 18x² - 6x
Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
So far we know the slope and can plug that into the equation like so...
y = -3x + b
Now we must find b
To do that you must plug in the point the line goes through in the x and y of the equation.
(4, -2)
-2 = -3(4) + b
-2 = -12 + b
10 = b
y = -3x + 10
Hope this helped!
