Answer:
C. (f - g)(x) = 3ˣ - 2x + 14
General Formulas and Concepts:
<u>Pre-Algebra</u>
<u>Algebra I</u>
- Function Notation
- Combining Like Terms
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3ˣ + 10
g(x) = 2x - 4
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 3ˣ + 10 - (2x - 4)
- Distribute -1: (f - g)(x) = 3ˣ + 10 - 2x + 4
- Combine like terms: (f - g)(x) = 3ˣ - 2x + 14
Answer:
9x^4 -x
Step-by-step explanation:
( -8x + 3x^4 ) - ( -7x - 6x^4 )
Distribute the minus sign
( -8x + 3x^4 ) +7x + 6x^4
Combine like terms
3x^4 + 6x^4 -8x +7x
9x^4 -x
