I don’t know how to do this problem and I need help can u help me plz

Question

F(x)=2^x

g(x)=2x-4

compare each function

Answer 1

F(x) is exponential.

g(x) is linear.

Answer 2

To compare these functions, graph then and check their value tables. You will see that for the same values of x, f(x) is growing faster than g(x).

g(x) has a constant rate of change (slope m = 2), it is an arithmetic sequence, a linear function

f(x) is an geometric sequence, where the consecutive values of y are multiplied by 2. (it is exponential growth)
