Answer:
Step-by-step explanation:
You haven't attached any graphs but as there area 3 distinct roots the graph will have 2 loops.
Also the end behaviour will be rising from the left negative values of f(x) and at the right it will rise to positive f(x).
Answer:
30 = total muffins
Step-by-step explanation:
To determine how many muffins were eaten, we take the total muffins times the fraction that were eaten
eaten muffins = total muffins * fraction
25 = total muffins* 5/6
Multiply each side by 6/5
6/5*25 = total muffins *5/6*6/5
30 = total muffins
The given equation is :
Divide both sides by 5
Add 0.3 to both sides.
Multiply a on both sides.
Hence 
... Answer
F(4) is function notation that means the value of y when x = 4.
Replace x with 4 in the expression and evaluate the right side.
f(x) = 3x - 15
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
Hey!
So we are given that the two lines (the one you are trying to find and the other one whose equation you have been given) are perpendicular. This means that their slopes are the negative reciprocal of each other. Since the slope of the line you have been given is -3 the slope of the line that you need to find is 1/3. Using this and the point we have been given we can find the y-intercept.
-4 = (1/3)(7) + b
-4 = 7/3 + b
-19/3 = b
Since we know both the slope and the y-intercept we can write out equation:
y = (1/3)x - 19/3
