Al you have to do is add 4 to the equation
This gives you g(x)=4x^2+9 which is your answer
Concave up is U-shaped.
There will be a inflection/critical point f'(x) =0 then a negative slope f'(x) = neg then another inflection/critical point f'(x) =0 at the bottom of the U-shape then a positive slope to last inflection/critical point. The interval for the Concave Up shape is the first and last inflection points.
We are given :
The ratio of orange juice to pineapple juice in tropical treat punch = 4:3 or 4/3.
Number of oz of orange juice = 64 oz.
Let us assume number of oz pineapple juice does he need = p.
We can setup an proportion:
64 : p = 4 : 3

On cross multiplication we get
64 × 3 = 4 × p
192 = 4p
Dividing both sides by 4, we get
p = 48.
<h3>Therefore, he needs 48 oz of pineapple juice.</h3>

This is found by the volume of a cone formula

Where b is the base and h is the height

your answer should be c.
A water balloon holds roughly 1.5 oz. of water
and pat has 19 water balloons to fill.
Multiply 1.5 and 19 and you get 28.5, or about 30 oz.
hope i helped!
