Answer:
A and C
Step-by-step explanation:
solving the equations
A
x² - 4 = 0 ( add 4 to both sides )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
B
x² = - 4 ← has no real solutions
C
4x² = 16 ( divide both sides by 4 )
x² = 4 ( take square root of both sides )
x = ± = ± 2 ← required solution
D
2(x - 2)² = 0 , then
x- 2 = 0 ( add 2 to both sides )
x = 2 ← not the required solution
Answer:
- g(x) = x² + 20x + 106
Step-by-step explanation:
<u>Given:</u>
If g(x) is the inverse of f(x), find it.
<u>Swap x with g(x) and f(x) with x:</u>
<u>Solve for g(x):</u>
