You will circle 4.5 on the number line. it should be an open circle going to the left side.
Answer:
To use the vertical line test, take a ruler or other straight edge and draw a line parallel to the y-axis for any chosen value of x. If the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function.

Answer:
Step-by-step explanation:
They are both technically right 7 time 9 is 63 but 7 time 9 is equivalent to 9 times 7
Answer:
b=2
c=-24.01
Step-by-step explanation:
If I understood your question right you need to find the constants b and c in the polynomial:

such that:

In order to get a system of two equations you can find limes when x goes to 4 from the right side or from the left side.
I solved this using a number that is close to 4. When it goes from right I used 4.1 and from left 3.9. This way you get two equations:

When you solve the system you get the answers above.
I think that the answer is 51/54.
First you need to find the common denominator of both fractions, 54.
1/9 is 6/54 and 5/6 is 45/54. 45+6=51. And the denominator goes on the bottom,making the answer 51/54.
Hope this helps!
