7 and 8 because the square root is 7.874
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
A cord: and the longest cord in a circle is the diameter , so a diameter is a special case of cord.
The translation that flips sides
