Algebra 2 (Practice Test) M1T1 Part 1

1.- Which equation does the graph represent?

• None of these

• It is a linear expression

• It is a quadratic expression

• It is an exponential expression

• None of this options

• Only functions in Pair A are equivalent
• Only functions in Pair B are equivalent
• Both Pairs of functions (A and B) are equivalent
• Neither Pair has equivalent functions

• a=4

  b=-2

  c=-6

• a=2

  b=-4

  c=-6

• a=6

  b=-4

  c=2

• a=-4

  b=6

  c=-2

• Concavity is positive because a>0, so it is Concave UP
• Concavity is positive because a>0, so it is Concave DOWN
• Concavity is negative because a<0, so it is Concave UP
• Concavity is negative because a<0, so it is Concave DOWN

• (0,2)
• (0,4)
• (0,6)

• (6,0)

• x=2
• x=-2
• x=1
• x=-1

• (1,-1)

• (-1,1)

• (-1,-1)

• (1,1)
