Under Daily flat rate, we would have 22 and 0.15x
Under Cost per mile, we would have 0.15
Under Number of Miles Driven, we would have x
Answer:
Step-by-step explanation:
Real coefients
if a+bi is a root then a-bi is also a root
since 3-i is a root then 3+i s also a root
also the √7, so if √7 is a root then -√7 is also a root
so
f roots are r1 and r2 then the factored form is
f(x)=(x-r1)(x-r2)
roots are 3-i, 3+i and √7 and -√7
f(x)=(x-(3-i))(x-(3+i))(x-√7)(x-(-√7))
expanded
f(x)=x⁴-6x³+3x²+42x-70
