The statements that are true considering the functions are provided as follows;
- W(n) = 4n+4 represents the function
- Input values for the function are natural numbers
- Figure 8 will have 36 white tiles.
What are the true statements?
The function that expresses the number of white tiles can be written as a function of the figure number. When these are expressed as ordered pairs, the results are;
(1, 8), (2, 12), (3, 16), (4, 20)
The first differences of the figures are all equal, therefore we can conclude that this is a linear situation. Next, we find the slope;
m = (12 - 8) / (2 - 1)
= 4/1
= 4
The point-slope form gives
y-8 = 4(x-1)
y - 8 = 4x - 4
y = 4x + 4
Substituting the value gives
y = 4*8 + 4
= 32 + 4
= 36.
