Answer:
y = x²
Step-by-step explanation:
y = x × x
1 = 1²
4 = 2²
9 = 3²
a(n) = (n-1)^2
Notice that each of the y-values {0, 1, 4, 9, 16, ... } is a perfect square. Thus,
the rule is a(n) = (n-1)^2.
Check: if n = 0, is (n-1)^2 = 0? yes
if n = 3, is (3-1)^2 = 4? yes
50%
due to the fact that its true/false questions, so that means when you answer you have 2 choices. a 50/50 chance of getting them right or wrong
