find f"(x) for f(x) = 4x - 6.
a. f''(x) = 4 b. f''(x)=4/x c. f''(x)=4x^3 - 6x^2 d. f''(x) = 0

Option 'D' is correct.

Step-by-step explanation:

Since we have given that

We need to find the double derivative i.e. f''(x).

So, we first derivate the f(x) w.r.t. x:

Now, we again derivative the f'(x) w.r.t x :

(Because f'(x) has no term with variable x)

Hence, Option 'D' is correct.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
