Answer:
x = 4i, − 4i
Step-by-step explanation:
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x
x = 4i, − 4i
These are the same line when you graph. So there are infinite solutions to this system.
Answer:
C
Step-by-step explanation:
The general rule for the quadratic function is

Use the data from the table:

We get the system of three equations:

Subtract these equations:

From the first equation

Substitute it into the second equation:

So,

The quadratic function is
