The function f(x) is shown on the graph.

if f(x) = 0, what is x?

0 only

–6 only

–2, 1, or 3 only

–6, –2, 1, or 3 only

c is the correct answer.

–2, 1, or 3 only

Step-by-step explanation:

The x-values of the points at which the graph touches the x-axis are the points at which

This is called the x-intercepts.

From the graph the x-intercepts are (-2,0),(1,0) an (3,0).

Therefore f(x)=0 at x=-2,1,3

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
