What are the zeros of the function?

Which of the following graphs correctly represents:

y=x²

y=-2x+1

• 
• 
• 
• 

When is f(x)=g(x)?
f(x) = x² + 3x - 5
g(x) = x + 3

• -4 and 1

• -4 and 2

• -4 and 2

• -4 and -1

Write the equation of the graph in factored form.

• f(x)=(x-4)(x+3)

• f(x)=-(x+3)(x-4)

• f(x)=(x+4)(x-3)

• f(x)=-(x-3)(x+4)

What are the solutions to this equation?
(3x-2)(5x+1)=0

• x=5/2,-1/3
• x=1/5,-2/3
• x=1/3,-5/2
• x=2/3,-1/5

x² + 12x = -35

• {-7, 5}
• {-9, -5}
• {-7, 0}
• {-7, -5}

Solve.

5b² - 4 = 41

• b = ±9

• b = ±3

• b = ±8

• No Real Number Solution
