Answer:
Options (B) and (C)
Explanation:
We have to form a function which has following characteristics,
1). Its range is all real numbers
Which means graph of the given function starts from negative side of the y-axis (-∞) and goes towards positive direction of the y-axis (+∞).
It's a typical characteristic of odd degree polynomial/function.
2). The graph has exactly two x-intercepts.
Which means when we put f(x) = 0, we get exactly two values of x.
Therefore, function will be, f(x) = x³ + x²
Range of the function → (-∞, ∞) Or a set of all real numbers.
x-intercepts → f(x) = x³ + x² = 0
x²(x + 1) = 0
x = -1, 0
Therefore, Options (B) and (C) will be the answer.
