1. The table shows a function.
1 answer:
Answer: a) Linear function
b) adding 8 each time x increases by 1
c) (0,13)
Step-by-step explanation:
For the given table, the rate of change is constant throughout the table.
The rate of change =
Similarly we can check for every interval, the rate of change remains constant .
Thus, it is a linear function and the pattern we observe here is "adding 8 each time x increases by 1".
We know that the ordered pair of y intercept = (0,y)
In the table at x=0, y=13
hence, the y intercept of the given function is (0,13)

Answer:
The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
Step-by-step explanation:
The fundamental theorem of algebra guarantees that a polynomial equation has the same number of complex roots as its degree.
We have to find the roots of this given equation.
If a quadratic equation is of the form
Its roots are and
