Precalc Semester 1 Final Review Day 2

When f(x) = 2x and g(x) = x²+3 , find f(g(x)).

• x²+2x+3
• 4x²+3
• 2x²+3
• 2x²+6

Which equation matches the graph?

• y = 2x + 3
• y = -3
• y = 2x - 3
• y = -3x + 2

Given -4 is a zero, find all other zeros
f(x) = x³+4x²+9x+36

• x = -2, 2
• x = -3, 3
• x =  -2i, 2i
• x = -3i, 3i

Simplify:
(3 + 2i) + (4i + 6)

• 9 + 6i
• 7i + 8
• 9 + 6i²
• 9 - 6i

Simplify:
(2 - 3i)(5 + 4i)

• 22 - 7i
• 22 + 7i
• 22 - 7i²
• 22 + 7i²
