F t > 0 , then √ ( t 2 + t ) ( t 3 + t 2 )/ ( t 2 + t ) + ( t 3 + t 2 ) =?

Ai just took the test

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
