Answer:
3, -8 , 11.
Step-by-step explanation:
f(x) = (x - 3)(x + 8)(x - 11)
Finding the zeros:
(x - 3)(x + 8)(x - 11) = 0
x - 3 = 0 gives x = 3.
x + 8 = 0 gives x = -8.
x - 11 = 0 gives x = 11.
X could be 6 or -2
You start at 2 on a number line and move 4 to the right and 4 to the left.
Ok so, y = mx + c is the equation of a line
When a graph is written in this form, m is the slope/gradient and c is the y - intercept.
This form is needed when a question asks for the equation.
Lets say they give 2 sets of coordinates, we can use the point slope formula to find the slope (m)
point slope formula:
(y₂ - y₁) = m(x₂ - x₁)
Then we substitute any of the two set of coordinates to find c, the y - intercept.
So the line has a gradient of m and y - intercept of c
5x(6+2) because 6+2=8 ans 5x8=40
