Which statement describes the graph of f(x) = –x4 + 3x3 + 10x2?
the graph crosses the x axis at x = 0 and touches the x axis at x = 5 and x = –2.
the graph touches the x axis at x = 0 and crosses the x axis at x = 5 and x = –2.
the graph crosses the x axis at x = 0 and touches the x axis at x = –5 and x = 2.
the graph touches the x axis at x = 0 and crosses the x axis at x = –5 and x = 2.

B is the answer, The graph touches the x axis at x = 0 and crosses the x axis at x = 5 and x = –2.

step-by-step explanation:

from the graph attached below:

domain of graph is the value of x for which the given function profit function p(x) is defined.

(a) the domain represents the number of years for which the outlet will earn a profit.

range of profit function defines the lowest to highest value of profit earned.

(b) the range of this function is (0 , 160 ). for this function, the range represents the outlet's profit earned.
