Needed asap
joe was given the recursive formula: f(1) = 3, f(n + 1) = f(n) - 7. to find the second term in the sequence, joe filled in the formula as followed: f(n + 1) = f(n) - 7 then f(n + 1) = f(2) - 7.

he explained since he is finding the second term in the sequence, the n should be replaced by 2.

if he is correct, what are the 2nd, 3rd and 4th terms?

if incorrect, show the correct formula.

f(1) = 4; f(n+1) = f(n) - 1.25

❤️Hello!❤️ f(1) = 4

f(2) = f(1) - 1.25 = 4 - 1.25 = 2.75

f(3) = f(2) - 1.25 = 2.75 - 1.25 = 1.50

f(4) = 1.50 - 1.25 = 0.25

f(5) = 0.25 - 1.25 = -1

f(6) = -1 -1.25 = -2.25

Sequence: 4, 2.75, 1.50, 0.25, -1, -2.25, ... Hope this helps! ↪️ Autumn ↩️

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
