Ответ:
Option C. is the correct option.
Step-by-step explanation:
From the graph attached for x = 0 y should be = 3.
Therefore, If we plug in the value x = 0, in the given functions y-value should be approximately 3.
A). y =![y=2\times 3^{x}](/tpl/images/0322/1546/e89d6.png)
y = 2
So this option is incorrect
B).![y=1.(3)^{x}](/tpl/images/0322/1546/89f1b.png)
y = 1
Incorrect option.
C).![y=3\times 2^{x}](/tpl/images/0322/1546/9d55f.png)
y = 3
This option is correct.
D).![y=4\times 3^{x}](/tpl/images/0322/1546/7fba4.png)
y = 4
Incorrect option.

it's answer is C. (3 , 0)
Step-by-step explanation:
given
y = x - 3
y = x² - 5x + 6
= x² - ( 3 + 2) x + 6
= x² - 3x - 2x + 6
= x ( x - 3) - 2( x - 3)
= ( x - 3) ( x - 2)
Now
we have y = x - 3
(x - 3) =( x - 3)( x - 2)
Both x -3 will be cancelled and we get
x -2 = 1
x = 1 + 2
x = 3
And now
y = 3 - 3
= 0
Hope it will help you :)
