The graph of f(x) = 2x3 +x2 – 4x – 2 is shown. how many of the roots of f(x) are rational? a.) 0 b.) 1 c.) 2 d.) 3

B) 1

Step-by-step explanation:

the correct answer is B:1

20

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
