Which formula defines the sequence f(1) = 2, f(2) = 6, f(3) = 10, f(4) = 14, f(5) = 18? a. f(1) = 2, f(n) = 6+ f(n-1) for n > (or equal to) 2
b. f(1) = 2, f(n) = 4 + f(n-1) for n > (or equal to) 2
c. f(1) = 2, f(n) = 2 + f(n-1) ffor n > (or equal to) 2
d. f(1) = 6, f(n) = 4 +f(n-1) for n > (or equal to) 2

step-by-step explanation:

b and c

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
