Given function:  Given the tunction f(x)= - x^2 + 4x - 3 ,find, №18011047, 03.11.2022 15:01

Given the tunction f(x)= - x^2 + 4x - 3 ,find, №18011047, 03.11.2022 15:01

Given the tunction f(x)= - x^2 + 4x - 3 ,find, №18011047, 03.11.2022 15:01

Given the tunction f(x)= - x^2 + 4x - 3 ,find, №18011047, 03.11.2022 15:01

Therefore, average rate of change over the interval -2 ≤ x ≤ 7

Step-by-step explanation:

Given function:  f(x)=-x^2+4x-3

\implies f(-2)=-(-2)^2+4(-2)-3=-15

\implies f(7)=-(7)^2+4(7)-3=-24

\textsf{Average rate of change}=\dfrac{f(b)-f(a)}{b-a}\quad\textsf{for}\:a\leq x\leq b

Therefore, average rate of change over the interval -2 ≤ x ≤ 7

\implies \textsf{Average rate of change}=\dfrac{f(7)-f(-2)}{7-(-2)}=\dfrac{-24-(-15)}{9}=-1

Cost before sale tax=$46.00

Cost after including tax=$48.76

Sale tax=$48.76-46.00

=$2.76

we know,

sale tax=((sales tax rate)/100) * cost before sale tax

2.76=((sales tax rate)/100) *46.00

sale tax rate=(2.76*100)/46

                   =276/46

                    =6%

There fore sales tax rate=6%
