Question
can you please simply explain how they get that domain and range espically where did they get a range of -2.25 from?
Transcribed Image Text:4. Suppose that f(r) e²r 5e + 4. Find the domain and range of
this function. Find all maxima and minima of this function. Plot the
function. Hint: the function can be factored.
The functions can be written: f(x) = (^^-4) (e^,)

= [A₁ ∞0) = √2.25, a
A= min value of the function and
we will find it soon.
