Line a is parallel to line b. If the measure of angle 2 is 78°, what is the
measure of angle 5?

Given f(x) = 17-x^2what is the average rate of change in f(x) over the interval [1, 5]?

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

Asequence has its first term equal to 4, and each term of the sequence is obtained by adding 2 to the previous term. if f(n) represents the nth term of the sequence, which of the following recursive functions best defines this sequence? (1 point) f(1) = 2 and f(n) = f(n − 1) + 4; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2n; n > 1 f(1) = 2 and f(n) = f(n − 1) + 4n; n > 1 f(1) = 4 and f(n) = f(n − 1) + 2; n > 1 i will award !
