Which of the following functions best describes this graph ?

Mathematics
1 answer:
IrinaVladis [17]3 years ago
7 0

Answer:

<h2> y = x{}^{2} - 9x + 20</h2><h2 />

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..

Best regards!!

Find the value of m .​
kondor19780726 [428]

Step-by-step explanation:

if the 2 matrices are inverse, then their product must be the identity matrix

1 0

0 1

so,

m×3 + 2×-7 = 1

7×3 + 3×-7 = 0

m×-2 + 2×m = 0

7×-2 + 3×m = 1

that means we have to solve only

3m - 14 = 1

3m = 15

m = 5

Which table represents the same linear relationship as the equation y = 5x + 7?
Nataly_w [17]
I can’t see the image. I’ll still try to help. The line has to cross 7 on the y-axis (|). The line is positive so it should look something like this “/“ By doing rise over run, (5/1) It is supposed to go up 5 times for every one time it goes to the right. Sorry if this explanation is a little confusing. This is the most I can do without seeing the image.
