It's linear
If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)
The formula for linear functions is y=mx +b
In this case b is 7
M=7-5/0+1
M=2
Now you just write the function down, it would be
F(x) =2x + 7
In order to answer this question the parts must be broken down: 8^3 is
8*8*8 which equals 512 and 8^5 is 8*8*8*8*8 which equals 32761.
512*32761 equals 16777216. 167772176 is greater than 1.
