Question

HI, I am looking for the answer to b) ii.

 

a. There is a function g relating values of y and z [y = g(x)]. Assuming it's defined, what do we know about g(7)? Choose all that apply.
Vg(7) is sometimes called an output value for function g.
Og(7) = 49.
Og(7) represents the value of a when y = 7.
From the given information, we don't know the exact value of g(7).
Vg(7) represents the value of y when æ = 7.
Vg(7) represents a y-value.
b. While sitting in a room, you notice a bug flying around. Let n represent the number of seconds since you noticed the bug and let d
represent the bug's distance from you in feet. Let f represent the function such that d = f(n).
i. Use function notation to represent the bug's distance from you (in feet) 8.5 seconds after you noticed it. Tip: Your answer should not
include an equal sign.
f(8.5)
Preview
ii. Use function notation to represent that the bug is 11 feet away from you some number of seconds after you noticed it. Tip: Your
answer should include an equal sign.
f(n)=11+d(n-1)
Preview
* Try again. What does f(n) represent in this situation? What information do you know? (Note: If you are trying to use inverse
function notation you should think of a different way to represent the given information. We do not know if the inverse
relationship is a function.)
