Which of the following functions best describes this graph ?

IrinaVladis [17]

Answer:

Step-by-step explanation:

As seen from the graph , the function cuts the x-axis at 4 and 5. So, the roots of function are 4 and 5.

The function becomes :

( x - 4 ) ( x - 5 )

Expanding:

$(x - 4)(x - 5)$

$x(x - 5) - 4(x - 5)$

${x}^{2} - 5x - 4x + 20$

${x}^{2} - 9x + 20$

So, after expansion , it becomes :

${x}^{2} - 9x + 20$

So, Option D is the correct option.

Hope this helps..

How do I factor e^2-10e+25

olga nikolaevna [1]

Answer: (e-5)^2

Step-by-step explanation:

The box method is a good way to solve this, but for a quick explanation, start by finding a single value that when added gets -10 and when multiplied gets +25. We can find that this term is -5. We the can situate -5 into (e-5)^2 equation, where if you FOIL, you will be back at the unfactored equation. Hope this helps
