Solve. draw and label a tape diagram to subtract 10, 20, 30, 40, etc.

17 - 9 = 18 - 10 =

-14 is the answer

hope this : ))

f(x) is   are being squared

g(x) is   increasing by 2

h(x) is adding .25 each time

k(x) is taking the square root

f(x) and k(x) are exponential functions

is there supposed to be a picture here?
