A quadratic function would fit this data.
The data does not increase at the same rate each time, so it is not linear. It comes to a maximum at (8, 150) and decreases. It decreases the same way it increased. This would lead to a U-shaped graph, which indicates a quadratic function.
Answer: X is 3 here. Haven't done this math (don't know how to graph) but I found x so it should be hard from here :)
Good Luck

Answer:
144, 36, 9, 2 
Step-by-step explanation:
The recursive formula allows us to find a term in a sequence from the previous term.
Given
= 
Given the fourth term we require to work back to the third term , second and so on. Rearrange the formula to give
Multiply both sides by 4, then
= 4
Given a₄ = 2 , then
a₃ = 4 × a₄ = 4 × 2 = 9
a₂ = 4 × a₃ = 4 × 9 = 36
a₁ = 4 × a₂ = 4 × 36 = 144
Answer:
m<B is 48°
Step-by-step explanation:
m<C is already 90°
m<A is 42°
42+90+x=180
132+x=180
x=48°
