The exponent of a linear function is 1.
exponent refers to the number of times a number is multiplied by itself.
For example: y = x + 3, Here all of them have exponent of 1.
.
This is considered to be a linear function. Linear is a straight line.
Another example: y = x² + 8. Here x has exponent of 2 and rest 1.
But it is not a linear function as does not follow the rule of linear function:
y = mx + b
