a, grocery store
b. -1,2
c. 0,4
d. 4th quadrant
A is x=1/3y + -2/3 for top one and x=-1/2y+1 for the bottom one
Answer:
31.1
Step-by-step explanation:
Y = log x / x
y ` = (( log x )` * x - (x)` * log x) / x²=
= (1/x * x - 1 * log x ) / x² =
= ( 1 - log x ) / x²
y ` = 0;
1 - log x = 0
log x = 1
x = e
The maximum value:
y max = log e / e = 1 / e
