Question

Which statements correctly describe the graph of the function f(x) = x3 – 4x2 – 3x + 18? Select three options.There are three unique solutions to the function when y=0.
The function has a double root.
As x increases from negative infinity to positive infinity, the y-values increase, decrease, and then increase again.
As x approaches negative infinity, y approaches positive infinity.
The domain and range of the function are the set of real numbers. , please hurry

Answer 1

@Hero @Vocaloid pls help

Answer 2

Have you tried graphing the function?

Answer 3

i did, i believe the second and fourth are correct im just not to sure about the third option

Answer 4

The third option is asking about the end behavior of the graph. Every point on the graph has the form (x,y). As x values get smaller and smaller, do y values get larger and larger?

Answer 5

yes the smaller the x value the higher the y value

Answer 6

Hmmm, x gets smaller and smaller are the y values getting larger AND positive?
