Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

f(x) = x + 3

g(x) = -x + 2

(f + g)(x) is f(x) + g(x)

<u>Step 2: Find</u>

  1. Substitute in function values:                                                                          (f + g)(x) = x + 3 - x + 2
  2. [Subtraction] Combine like terms (x):                                                              (f + g)(x) = 3 + 2
  3. Add:                                                                                                                   (f + g)(x) = 5

What is the base five representation of The number 219
ICE Princess25 [194]

assuming 219_{10}

Then the column values for base five here are

5³  5²  5^{1}  5^{0}

We can get 1 × 5³ = 125 → 219 - 125 = 94

We can get 3 × 5² = 75 → 94 - 75 = 19

We can get 3 x 5^{1} → 19 - 15 = 4

and 4 = 4 × 5^{0}

Thus 219_{10} = 1334_{5}

As a check

(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219

I'm not entirely sure what you mean but simplifying this expression results in 96x + 5 1/2.

What is the domain of f?
Sedbober [7]

The domain of a function is the set of all possible inputs for the function. For example, the domain of f(x)=x² is all real numbers, and the domain of g(x)=1/x is all real numbers except for x=0.
