STEP 2: Find the mean

mean is 87.33
STEP 3: Find the median
Answer:
f(0) = 1
Step-by-step explanation:
f(0) means what is the value of y when x = 0
from the diagram this is the point (0, 1 ) , then
f(0) = 1

combining x and -4.87x on the left,
adding -35.39 to both sides we get,
dividing both sides by -3.87, we get
Answer : x=-29.354
