y=-x^3+4x--describe the end behavior of the graph

Question

describe the end behavior of the graph of the polynominal function.then evaluate x=-2,-1,0,1,2------- y = -x^3+4x------ problem #2))) x=-2,-1,0,1,2---y=3x^3-9x+1

Answer 1

y=x^3 +4x...????end... zat meen for big x ???

wen x big,  y=x^3, so kerv go up steep & steeper

for big negativ x, it go down steep
