Write an equation of the line passing through (1, -11) and (-4, -1)

Step-by-step explanation:

Slope = (-1+11)/(-4-1) = 10/-5 = -2

Equation of a line is

y +11 = -2(x-1)

y = -2x +2 -11

y = -2x -9

g(4x) = 192x^3

Step-by-step explanation:

For this problem, f(x) is irrelevant since we are simply are dealing with g(x).  We will simply replace the value of x in g(x) with 4x.  So let's do that.

g(x) = 3x^3

g(4x) = 3(4x)^3

g(4x) = 3(4^3)(x^3)

g(4x) = 3(64)(x^3)

g(4x) = 192x^3

Hence, g(4x) is 192x^3.

Cheers.
