Given f(x) = -8x+6 and g(x) = x^3 choose the expression for (f of g)(x)

(f o g)(x) is the composition of function where we substitute one function into other function.

So, (f o g)(x) = f( g(x) )

The given functions are f(x) = -8x+6 and g(x) = x³.

So,we need to plug in x³ for g(x) in f(x). Therefore,

(f o g)(x) = f( g(x) )

= f (x³) Replace g(x) with x³.

= -8x³ + 6 Replace x³ with x in f(x).

So, (f o g)(x) = -8x³ + 6.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
