Name the functions of the graphs a, b, c, d

Explanation:

Graph ‘a’

This clearly represents the equation y = mx.

m: slope of the line.

If the slope is positive the graph will be:

If the slope is negative the graph will be:

Graph ‘b’

Graph ‘c’

The exponential rising function is shown below:

f(x) = e^x

Graph ‘d’

Consider the equation y = mx + c

The graph is shown below:

C: intercept on the ‘y – axis’

Conclusion:

The graphs are:

a: f(x) = x

b: f(x) = |x|

c: f(x) = e^x

d: f(x) = x + 2
