Answer:
18
Step-by-step explanation:
Evaluate g(2), then substitute the value obtained into f(x)
g(2) = 2² - 1 = 4 - 1 = 3 , then
f(3) = 2(3)² = 2(9) = 18
Answer: B
No real solutions.
x² + 6x + 10 = 0
a = 1
b = 6
c = 10
D = b² - 4ac = 6² - 4*1*10 = 36 - 40 = - 4
- 4 < 0,
so this equation has no real solutions.
