Answer:
6 and 7
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x) , that is
f(3) = 2(3) = 6
To evaluate g(f(3)), substitute f(3) = 6 into g(x)
g(6) = 6 + 1 = 7
Answer:
x² - x - 12 = 0
Step-by-step explanation:
0 = -x² + x + 12
→ Add x² to both sides
x² = x + 12
→ Minus x from both sides
x² - x = 12
→ Minus 12 from both sides
x² - x - 12 = 0
