Answer:
f(4) = 5
Step-by-step explanation:
f(x) = 5.
Whatever value of x you input to the function , the function's value is always 5.
This is seen when you examine the graph of f(x) = 5. It is a straight horizontal line passing through y = 5. For every value of x along the line, f(x) = y = 5.

Answer:
C. 42
Step-by-step explanation:
<em>PEMDAS</em>
1. Parentheses: (4 + 2) = <em>6</em>
6² + 3 • 2
2. Exponents: 6² = <em>36</em>
36 + 3 • 2
3. Multiplication/Division: 3 • 2 = <em>6</em>
36 + 6
4. Addition/Subtraction: 36 + 6 = <em>42</em>

Answer:
x = ± 2.45
Step-by-step explanation:
Given
8x² - 48 = 0 ( add 48 to both sides )
8x² = 48 ( divide both sides by 8 )
x² = 6 ( take the square root of both sides )
x = ±
= ± 2.45 ( nearest hundredth )
