If f(1) = 2 and f(n) = f(n − 1)2 + 3 then find the value of f(3).
blondinia [14]

Answer:

52

Step-by-step explanation:

f(n) is purely based on the previous value of f(n), or f(n-1), so we can start with f(1) and work our way up. We know f(1) = 2, so to find f(2), we plug f(1) into

f(n-1)²+3 to get

f(1)²+3 = 2²+3 = 4+3=7

Thus, f(2) =7. Similarly,

f(3) = f(3-1)²+3 = f(2)² + 3 -= 7² + 3= 52

If f(x)=2x^2 + 5 sqrt(x-2), complete the following statement f(6)
Alenkinab [10]

Answer:

f(6) = 82

Step-by-step explanation:

substitute x = 6 into f(x) and evaluate

f(6) = 2(6)² + 5\sqrt{6-2} = 2(36) + 5\sqrt{4} = 72 + 5(2) = 72 + 10 = 82

18x + 9y use the distributive property to write an equivalent expression
kirza4 [7]
Hey there!
It looks like you have another factoring question!
Using our definition of the distributive property:
a(b+c) = ab+ac
We need to factor our or greatest common multiple, which here is 9.
9 times 2x = 18x and 9 times y = 9y
We have:
9(2x + y)
Once again, using the distributive property, multiply it out and you'll get 18x and 9y.
Hope this helps!
