What is the domain and range of the following equation?

Question

4x³ - x⁵

Answer 1

domain and range are all real numbers

4x^3 -x^5

when x=0, the polynomial = 0

x<0, the polynomial approaches infinity as x approaches -infinity

for x>0, the polynomial approaches -infinity as x approaches infinity

no value of x is excluded,

no value of the polynomial is excluded

graph the polynomial, the curve has no global max or minimum

and no limit on x values
