The function
is a constant, representing a horizontal line at
. It's a linear function but lacks a slope or rate of change, maintaining a constant value of
for all
.
The function
represents a constant function where the output (or
is always
regardless of the input (or
).
In this case, the function doesn't have a variable term
or any slope because it's a horizontal line parallel to the x-axis at a height of
.
Given function :

Explanation: The function is a horizontal line at
on the Cartesian plane.
Slope: Not applicable as the function doesn't have a variable term
to determine a slope. It's a constant function, so there's no change in
with respect to
.
Rate of change: There's no rate of change since the function's output remains constantly
for all
values.
Therefore, the function
is indeed a linear function (a horizontal line), but it doesn't have a slope or a rate of change as it represents a constant value of
.
complete the question
Is f(x) 6 a linear function?
Yes, f(x) 6 is a linear function.
No, f(x) = 6 is not a linear function.
If so, what are the slope and the rate of change? (If the function is not linear, enter NOT LINEAR.)
