Question

Which polynomial function could be represented by the graph below?

Answer 1

Answer:

$f(x)=3x^2-18x+24$

Step-by-step explanation:

we are given a graph

we can see that graph is of parabola

so, the function will be quadratic in nature

Firstly, we can identify zeros

zeros are x=2 and x=4

now, we can set up function

$f(x)=a(x-2)(x-4)$

now, we can select anyone point and find 'a'

at x=3 , y=-3

we can use it and find 'a'

$-3=a(3-2)(3-4)$

$a=3$

now, we can plug it back

and we get

$f(x)=3(x-2)(x-4)$

we can multiply it

and we get

$f(x)=3x^2-18x+24$

Answer 2

Answer:

f(x) = 3x^2 – 18x + 24
