Semester 2 review

In which step does a mistake first appear?

• Step 1

• Step 2

• Step 3

• Step 4

Which graph shows a function with a domain of all real numbers greater than 7?

• 
• 
• 
• 

What is the value of x in the solution to the system of equations?

• 1

• 5/3

• 8/3

• 7/3

Is this a max or min?

• max
• min
• cannot be determined

True or false:
The solution, root, x-intercept, and zero of a problem are all the same thing

• True
• False, because the solution and root are the same but the x-intercept and zero are different
• False, because the x-intercept and root are the same but the zero and solution are different
• False, they are all different

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

Does the following quadratic equation have a maximum or minimum value? How can you tell?
y=x²+2x-3

• Minimum value, because the a value is positive
• Maximum value, because the b value is positive
• Maximum value, because the a value is positive
• Minimum value, because the c value is negative

Solve the equation using the quadratic formula.

• A
• B
• C
• D

What is the arrow pointing at? How can you use this value?

• The arrow is pointing at the y-intercept. The x-value is the axis of symmetry and the y-value of this point is equivalent to the maximum/minimum 
• The arrow is pointing at the vertex. The x value of this point is equivalent to the maximum/minimum and the y-value is the axis of symmetry
• The arrow is pointing at the solution. The y value of this point is equivalent to the maximum and the x value is equivalent to the minimum
• The arrow is pointing at the vertex. The x-value is the axis of symmetry and the y-value is equivalent to the minimum/maximum

Solve using the quadratic formula

• A 
• B 
• C 
• D
