Draw graph for y=3x-1

What is the best approximation for the area of a circle with a radius of 4 m ? use 3.14 to approximate pi

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
