For this case we have the following function:
f (x) = (1/3) * (4 ^ x)
We must evaluate the function for x = 2
We have then:
f (2) = (1/3) * (4 ^ 2)
Rewriting:
f (2) = (1/3) * (16)
f (2) = 16/3
Answer:
The function evaluated at x = 2 is:
f (2) = 16/3
option A
I do not think all of the question is there.
25 X y = / y would have to
Answer:
<u>f(x) = 50 + 25(x - 1)</u>
Step-by-step explanation:
Let's write an equation to represent the function that will allow Damon to calculate the cost of his video game membership service:
Lifetime membership fee = $ 50
First video game is free
Then any video game purchased after = $ 25.
Let x to represent the total cost of the video game membership service, in consequence we can write the equation this way:
<u>f(x) = 50 + 25(x - 1)</u>
- If x = 1, then f(1) = 50 + 0 = 50
- If x = 2, then f(2) = 50 + 25 = 75
- If x = 5, then f(5) = 50 + 100 = 150
Answer:
D
Step-by-step explanation:
To convert from polar to rectangular form
• x = rcosΘ , y = rsinΘ
• r = 
⇒ r² = x² + y²
Given
r = 8cosΘ
r = 8 × 
( multiply both sides by r )
r² = 8x, hence
x² + y² = 8x ⇒ D
