Without a calculator match each of the eight graphs below wi

Without a calculator, match each of the eight graphs below with a function in the table. Many functions will not be matched to any of the eight graphs. Enter the letter A-X of the function below its corresponding graph.

Solution

i. H

because the graph is linear and in the equation, y=-4 when x=0

ii.Cannot say with out complete graph

iii. Cannot say with out complete graph

iv. A

it is sinusoidal signal with maximum amplitude and maximum time period (compared with another waveform viii)

v. Cannot say with out complete graph

vi. T

because the curve is exponential curve.

In the equation given in T

y=-3 when x=0 and y=0 when x is infinite.

All these are satisfied in the given curve.

vii. Cannot say with out complete graph

viii. B

it is sinusoidal signal with minimum amplitude and minimum time period (compared with another waveform iv)
