Answer:

x = 1.723

Step-by-step explanation:

The  zeros of a function f(x) are the points where the function crosses the x-axis. At these points, the function will have a value of zero, that is;

f(x) = 0

We simply graph the function and determine the points where it crosses the x-axis. From the attachment, f(x) crosses the x-axis at;

x = 1.723

Answer:

Step-by-step explanation:

We have given the function:

f(x)=-3x³+6x+5.

We have to find the zeros of the function.

The zeros of the function are the points where the function cuts the x-axis.

And at that points function has value zero.

So to find these points put f(x)= 0 we get,

-3x³+6x+5=0

As from the graph the function cuts the x-axis at x = 1.723 so, this is the zero of the function.

Slope = 4, passing through (-6, 8)
Mademuasel [1]

The point slope form is y - 8 = 4(x + 6) and the slope intercept form would be y = 4x + 32.

In order to find this, we'll start with the base form of point-slope form.

y - y1 = m(x - x1) ----> Plug in the numbers

y - 8 = 4(x - -6) ----> Simplify

y - 8 = 4(x + 6)

Now to find slope intercept form, solve for y.

y - 8 = 4(x + 6) ----> distribute the 4

y - 8 = 4x + 24 -----> add 8 to both sides

y = 4x + 32
