Answer:
Hlooo em dng like the same time as a great day of the same time as a great day of the same time as a great day may I have a good time for
Y =ax² + bx +c
1) Point (0,7)
7 = a*0² +b*0 +c
c = 7
y=ax² + bx + 7
2) Point (1,4)
4=a*1² + b*1 + 7, ----> 4 = a +b + 7, ------>
a+b= - 3
3) Point (2, 5)
5=a*2² + b*2 + 7, ----> 5=4a+2b +7,---> -2=4a+2b, ---->
-1=2a + b
4)
a+b= - 3, ----> b= -3 - a (substitute in the second equation)
2a+b= -1
2a - 3 - a = -1, ----> a - 3 = -1,
a =2
5) a+b= - 3
2 + b = -3
b = -5
y=2x² - 5x + 7
Answer:
number 3
Step-by-step explanation:
(3,000+900+70) = 3,970
3,970*10 = 39,700
ANSWER

EXPLANATION
The given function is

When we plug in x=3 into this function, we obtain,

This means that the function is discontinuous at x=3.
We need to simplify the function to obtain,

This implies that,

The graph this function is a straight line that is continuous everywhere.
To graph

we draw the graph of

and leave a hole at x=3.
See diagram in attachment.
Hence the coordinates of hole is
