a) Increasing function.

b) The growth factor is 4.

c) The asymptote is y tending to zero as x tends to negative infinity.

d) y = 1

c) The graph can be seen at the end.

<h3>What conclusions can we get about the given function?</h3>

Here we are given the following exponential function:

y =f(x) =  4^x

a) First, we want to know if the function is increasing or decreasing. Remember that a function is increasing if, as x increses, also does the value of y.

Here clearly we have an increasing function.

  • f(0) = 4^0 = 1
  • f(1) = 4^1 = 4
  • f(2) = 4^2 = 16

and so on...

b) Now we want to identify the growth factor. This is the number that is being exponentiated, so in:

y = 4^x

The growth factor is 4.

c) We have an asymptote as x tends to negative infinity, because we will eventually have denominator that tends to infinity, then we will have an asymptote that tends to zero, as x tends to negative infinity.

d) The y-intercept is what we get when we evaluate in x = 0, we have:

y = f(0) = 4^0 = 1

The y-intercept is y = 1.

e) The sketch of the exponential function can be seen in the image below.

Kim, Laura and Molly share £385 The ratio of the amount of money Kim gets to the amount of money Mollly gets is 2:5 Kim gets £10
Thepotemich [5.8K]
<span><span>Molly: 105 x 05/02 = 42</span>
Kim: 105-42</span> = 63
<span> Laura: 385-105 = 280
           280 x 100/385</span><span> = 72%
Donc Laura obtient  72</span>%
