Question 1

The area of a triangle is 10 square meters. If the height is 8 meters longer than the base, find the length of the base and the height of the triangle. Fill in the blank.

Answer: The length of the base of the triangle is   meters and the height of the triangle is   meters.

·         100

·         64

Question 2

What function represents the given graph?    

·         f(x)=(x+1)2f(x)=(x+1)2  

·         f(x)=(x−1)2f(x)=(x−1)2  

·         f(x)=x2+1f(x)=x2+1  

·         f(x)=x2−1f(x)=x2−1    

·         none of the above

Question 3

What function represents the given graph?    

·         f(x)=(x−2)2−2f(x)=(x−2)2−2  

·         f(x)=−(x−2)2+2f(x)=−(x−2)2+2  

·         f(x)=−(x+2)2+2f(x)=−(x+2)2+2    

·         f(x)=(x+2)2−2f(x)=(x+2)2−2  

·         none of the above

Question 4

·         (-7,-3)  

·         (-7,3) 

·         (7,3)  

·         none of the above

Question 5

Write the following quadratic function in the form f(x)=a(x−h)2+kf(x)=a(x−h)2+k  by completing the square. Type in your answer and use the "^" for the power, for example to type in  x2x2 , you type x^2. The caret (^) button is often found using shift 6.
