Question

(a) use a graphing utility to graph the equation, y=2x^4-15x^3+18x^2.

(b) use the graph to approximate any -intercepts of the graph,

(c) set y=0 and solve the resulting equation, and

(d) compare the result of part (c) with the -intercepts of the graph.

Answer 1

(a) Graph of the equation y=2x^4-15x^3+18x^2 is

(b) The x-intercept is the value of x when y = 0.

The x-intercept values are .

(c) This problem same as (b) problem.

(d) The x - intercepts and the solutions are same, Those are .
