How does f(x) = 3x change over the interval x = 4 to x = 5

Select the sequences that are geometric.

1c) the number 131 is a term in the sequence defined by the explicit rule f(n)=5n-4. which term in the sequence is 131? 2a) write the first four terms of the function f(n)=n^2-1 2b) what is the 10th term of the sequence defined by the explicit rule f(n)=n^2-1 2c) the number 224 is a term in the sequence defined by the explicit rule f(n)=n^2-1. which term in the sequence is 224?

What value is a discontinuity of x squared plus 8 x plus 4, all over x squared minus x minus 6?
