Let f(x) f ( x ) be the function whose graph is shown below. Determine f′(a) f ′ ( a ) for a=1,2,4,7 a = 1 , 2 , 4 , 7 . f′(1)= f ′ ( 1 ) = f′(2)= f ′ ( 2 ) = f′(4)= f ′ ( 4 ) = f′(7)=

Given that (x-3) is a factor of f(x)=x^3+ax^2-x-6, find a and hence the number of real roots or the equation f(x)=0

The inside wheels of a car traveling on a circular path are rotating half as fast as the outside wheels. the front two wheels are six feet apart. what is the number of feet in the path traced by the inside front wheel in one trip around the circle? express your answer in the form "k \pi", where k is an integer.

Idon’t understand this.. will someone ? will mark brainliest along with 20 points.
