You'll need to multiply the function out to get it in the form y = ax^2 + bx + c, in this case it would be y = 4x^2 + 16x + 20.
We can immediately see that y = 20 would be the y value for the pivot point for the equation, and since the equation is positive it woukd have a concave shape. Thus it woulc be a minimum of 20, since there are no points lower than that on the y-axis.
Plotting functions like this on desmos helps you get a better understanding of how they work. I recommend you try! ;)
Answer:
2 mph
Step-by-step explanation:
Since Jenny can do 1/2 of a mile in 1/4th of an hour, she can do twice as many miles, which is 1/2
Answer:
We'll use the traditional "slope" formula, evaluating
To find f(5), plug in x = 5 to f(x).
3(5)^3 + 2 = 377
Same thing for f(3)
3(3)^3 + 2 = 83
So
Answer:
The answer is the last one
Y=4x+2 on (0,3) so start at the point (0,3) then go up 2 and there is your answer!
