Answer:

20  

Step-by-step explanation:

ƒ(x) = 3x² – 2

g(x) = 4x + 2

1. Add the functions

By definition,  

(ƒ + g)(x) = ƒ(x) + g(x)

3x²          - 2

<u>       + 4x + 2 </u>

3x² + 4x

(ƒ + g)(x) = 3x² + 4x

2. Evaluate (ƒ + g)(2)

(ƒ + g)(2) = 3(2)² + 4(2) = 3(4) + 8 = 12 + 8 = 20

Answer:

\displaystyle 20 = (f + g)(2)

Step-by-step explanation:

\displaystyle [4(2) + 2] + [3(2)^2 - 2] = [8 + 2] + [3(4) - 2] = 10 + [12 - 2] = 10 + 10 = 20

I am joyous to assist you anytime.

You make punch for a party. The ratio og ginger ale to fruit juice is 8 cups to 3 cups. You decide to add 4 more cups of ginger
Dvinal [7]
To get the answer we can use proportion
8 ginger ----------------- 3 fruit
12 ginger ----------------x
Crossmultiply now
8x=12*3                /:8
x=\frac{12*3}{8}
x=<u />\frac{36}{8}  \\ x=4.5
To not change ratio we have to have 4.5 cups of fruilt juice. We initialy had 3, so we have to add 1.5 cup of fruit juice.
