Answer:
The first one: {{7, 12), (1, -5), (3, -10), (2, -5)}
Step-by-step explanation:
Functions can't have repeating x values. Each x has to have its own y value.

f(x) = x² + 14 g(x) = x - 2 -1 ? I think it means evaluate when x = -1
Find (f(x) + g(x)) when x = -1
(f(x) + g(x)) = [ ( x² + 14) + (x - 2)] insert f(x) and g(x)
= [ x² + x + 14 - 2] add like the term
(f(x) + g(x)) = x² + x + 12
(f(-1) + g(-1)) = (-1)² + (-1) + 12 evaluate at x = -1
= 1 - 1 + 12
= 12
Answer:
10%
Step-by-step explanation:
a simple way to put it is 50 * 2 is 100, 5 * 2 is 10, so 10/100 is 10%
Answer:
is a factor of 
Step-by-step explanation:
is a factor of
We will prove this with the help of principal of mathematical induction.
For n = 1, is a factor , which is true.
Let the given statement be true for n = k that is is a factor of 
.
Thus, can be written equal to 
, where y is an integer.
Now, we will prove that the given statement is true for n = k+1
Thus, is divisible by .
Hence, by principle of mathematical induction, the given statement is true for all natural numbers,n.
