Question

Find the zeros of each functions by using a graph and a table. F(x)=x^2+9x+14

Answer 1

Zeroes of a function are the values of x when f(x) = 0

So to find the zeroes of the function from the graph search for the points whose y-coordinates = 0

The y-coordinates of the point = 0, if the points lie on the x-axis

That means the zeroes of the function are the points of intersection between the graph and the x-axis

let us see that in the graph

I will draw it and post it here

From the graph

The graph intersects x-axis at points (-7, 0) and (-2, 0)

Then the zeroes of the function are (-7, 0) and (-2, 0)

Let us make the table

x f(x)

-2 0

-1 6

0 14

1 24

2 36
