Martin says that f(x)=2(4)^x starts at 4 and has a constant ratio of 2. What error did Martin make? Explain.
grigory [225]

Answer:

A general exponential equation is written as:

f(x) = A*(r)^x

Where:

A is the initial value, this is the value that the function takes when x = 0.

r is the rate of growth

x is the variable.

In this case, the function is:

f(x) = 2*(4)^x

The initial value is:

f(0) = 2*(4)^0 = 2*1 = 2

The initial value is 2.

And the rate of growth is 4.

So Martin seems to mixed these two values (he said initial value = 4, and rate  = 2, which is the opposite of what we found)

The function f(x)=5(2)^x was replaced with f(x)+k , resulting in the function graphed below. what is the value of k?
xxTIMURxx [149]
Since adding a constant to a function simply moved the graph upwards by that amount, solve f(x) for any value and see how much the graph given is different from that value of y...the simplest way in this case may be to simply find f(0) which is:

5*2^0=5

Clearly the graph at x=0 is at y=-2  so we can see that k is:

5+k=-2 so

k=-7

Can someone help me please?

Looking at the graph, trace your finger up from 10 on the x-axis. You will end up somewhere around 17.

Therefore, the approximate height of the tree after 10 years will be 17 feet.
