Answer:
f(x) has three real roots.
Step-by-step explanation:
f(x) has three real roots.
A third degree polynomial function with real coefficients has exactly 3 roots.
Furthermore, all complex roots come in pairs, either there is none, or there are exactly two conjugates, which are in the form e1+i(e2) and e1-i(e2) where e1 and e2 are polynomial expressions.
This also means that a third degree polynomial with real coefficients has at least one real root, or three.
Since we are given two real roots for the given polynomial, the third root cannot be complex alone, so the only possibility is that there are three real roots.
Given, the charges to clip a dog's nail = $n
The charges to wash the dog = $w
The charges to cut a dog's hair = $h
The total charges Jasmin take for 1 dog = $n+$w+$h = $(n+w+h)
For 4 dogs we can get total charges by multiplying the total charge for 1 dog with 4.
So, the total charges for 4 dogs = $(n+w+h) × 4 = $ 4(n+w+h) = $(4n+4w+4h)
So we have got the required answer.
The total charges for 4 dogs = $ 4(n+w+h) = $(4n+4w+4h)
