The graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
<h3>How to determine the graph of the function?</h3>The equation of the function is given as:
f(x)=3(2)^x -4
Set x = 0, 1, 2 and 3
f(0)=3(2)^0 -4 = -1
f(1) = 3(2)^(1) - 4 = 2
f(2) = 3(2)^(2) - 4 = 8
f(3) = 3(2)^(3) - 4 = 20
This means that the graph of the function f(x)=3(2)^x -4 passes through the points (0,-1), (1,2), (2,8) and (3,20)
