Consider the function shown on the graph.
Which function does the graph represent?

a.f(x) = (x + 3)(x + 7)
b.f(x) = (x – 3)(x – 7)
c.f(x) = 3(x – 3)(x – 7)
d.f(x) = 11(x + 3)(x + 7)

Respuesta :

The answer is the third graph.

Answer:

Option (c) is correct.

The function is [tex]f(x) =3(x-3)(x-7)[/tex]  

Step-by-step explanation:

Given : A graph with two zeros at (3,0) and (7,0)

We have to find the function that shows the given graph.

Consider the given graph

Since, (3,0) and (7,0) are the zeros,

The value of function is 0 at 3 and 7

That is f(3) = 0 and f(7) = 0

Thus,

x = 3 and x = 7

That is x - 3 = 0 and x - 7 = 0

That is (x-3)(x-7)=0

Also, when x= 8 then y = 15 is satisfies by only by option (c)

f(x) = 3(x-3)(x-7)

Thus, The function is [tex]f(x) =3(x-3)(x-7)[/tex]
