The true statement is the graph of the function crosses the x-axis at x = x = 0, 1.34 and 7.97
The function is given as:
[tex]\mathbf{f(x) = x^5 - 8x^4 + 16x^3}[/tex]
See attachment for the graph of [tex]\mathbf{f(x) = x^5 - 8x^4 + 16x^3}[/tex]
From the attachment, we have the following highlights
- The graph crosses the x-axis at all points it touches the x-axis,
- The graph of the function crosses the x-axis at x = x = 0, 1.34 and 7.97
Hence, the true statement is (b) above
