Answer: f(f(f(x)) = 8x - 7
Step-by-step explanation:
f(f(x)) means that we are evaluating f(x) with itself, then if f(x) = 2x - 1
f(f(x)) = 2*f(x) - 1 = 2*(2x - 1) - 1 = 4x - 2 - 1 = 4x - 3
f(f(x)) = 4x - 3
Then, we have f(f(f(x)) = 4*f(x) - 3
= 4*(2x - 1) - 3 = 8x - 4 - 3 = 8x - 7
This question requires you to solve,
(y²)⁵×y⁸ =y⁽²ˣ⁵⁾ × y⁸
= y¹⁰ × y⁸
= y⁽¹⁰⁺⁸⁾
= y¹⁸
The correct answer is y¹⁸
Answer:
A function is a rule that takes an input, does something to it,
and gives a unique corresponding output.
There is a special notation, called "function notation," that is used to represent this situation:
if the function name is f , and the input name is x ,
Step-by-step explanation:
The time it takes between when the rock was dropped and when it landed is 1.33 seconds.
<h3>What is the time it takes for the rock to land?</h3>
The time it takes the rock to land on the ground from where it is dropped can be determined by using the function given.
The height of the function when it hits the ground will be zero, so the function can be written as:
64 = 36t²
t² =1.778
t = 1.333 seconds
