Hi there!
Question 1: Answer: -
20 x 4 - 80 = 80 - 80 = 0
Question 2: Answer: +
100 x 100 + 1 = 10,000 + 1 = 10,001
Answer:
211
Step-by-step explanation:
Answer:
U shaped.
Step-by-step explanation:
When x = 0 , f(x) = 6
when x =1 yf(x) = 0
when x = 2 f(x) = -2
x = 3 f(x) = 0
x = 4 f(x) = 6.
So the graphs falls from the left and rises to the right in the form of a U.
You can draw a rough graph to confirm this.
<h3>
It is a function</h3>
Why? Because each input maps to <u>exactly one</u> output. The input oval represents the domain (set of all possible inputs). The output oval is the range, which is the set of all possible outputs. If we had something like the input 0 mapping to the outputs 2 and 4 at the same time, then we wouldn't have a function.
