Answer:
The graph attached represents an exponential function.
Step-by-step explanation:
An exponential function is represented by a hyperbola which shows some proportionality on the numbers.
The common thing about exponential functions is that they reach infinity.
One example of an exponential function is the graph of
The graph is a hyperbolic curve that continues without a definite value.
Another example of such a graph is the graph of :
As the value of y increases, the graph reaches closer and closer to the x- axis but takes forever to reach such a value of intersection.
We say such graphs reach infinity with the y-value.

Answer:
n = 8
Step-by-step explanation:
Continuing the sequence using
+
x₄ = x₂ + x₃ =1 + 2 = 3
x₅ = x₃ + x₄ = 2 + 3 = 5
x₆ = x₄ + x₅ = 3 + 5 = 8
x₇ = x₅ + x₆ = 5 + 8 = 13
x₈ = x₆ + x₇ = 8 + 13 = 21
x₉ = x₇ + x₈ = 13 + 21 = 34
x₁₀ = x₈ + x₉ = 21 + 34 = 55 ← with n = 8
