Question

WHERE'S ALL THE LIFE SAVERS?!

Algebra functions. forget how ?

Answer 1

#8 y-intercept is when x = 0. Put x = 0 and calculate f(x). For g(x) look up the table for g(x) when x = 0.

Answer 2

you are welcome.

Answer 3

#9) Look at the pattern in the f(x) row.
They are all powers of 3: 3 = 3^1, 9 = 3^2, 27 = 3^3, ...3^x
So f(x) = 3^x
g(x) = 4 (always)
Therefore, f(x) - g(x) = ?
