Question

Sketch the graph of the exponential function.

f(x)=(0.2)^x

Answer 1

`(1)/(0.2) = ( (1)/(1) )/( (2)/(10) ) = (10)/(2) = 5 \: and \: 1 \: and \: 0.2`

Explanation:

f(x) = (0.2)^x

x = -1

f(-1) = 0.2^-1 = 1/0.2 = 1/1/2/10 = 10/2 = 5

x = 0

f(0) = 0.2^0 = 1

x = 1

f(1) = 0.2

These would be the values for y, then you need to make a graph using them and the ones for,
