Log(7)+log(x-4)=1
log(7(x-4))=1 by the law of logarithms

ASSUMING log is to the base 10,
then by the law of logarithms, [10^log(x)=x]
7(x-4)=10^1=10
solving for x
x=(10/7)+4=38/7

Given the tunction

natulia [17]

Answer:

-1

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

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