Answer:

y = 15x^3 + 16x^2 - 55x + 24

Step-by-step explanation:

y = (3x +8)(5x - 3)(x - 1)

y = (15x^2 - 9x + 40x -24) * (x - 1)

y = (15x^2 + 31x - 24) * (x-1)

y = 15x^3 - 15x^2 + 31x^2 - 31x - 24x + 24

The x-intercepts of a graph are the points where the graph crosses the x-axis.

The x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

The function is given as:

[tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

First, we plot the graph of [tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

See attachment for the graph

Next, write out the x-values when the graph crosses the x-axis.

From the graph, we have:

[tex]\mathbf{x = -\frac 83}[/tex]

[tex]\mathbf{x = \frac 35}[/tex]

[tex]\mathbf{x = 1}[/tex]

Hence, the x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]
