  Which quadratic function in vertex form has a vertex at (-2,20) and passes through a point at (3,10)?

Given the table, what are the a, b, and c values (rounded to the nearest hundreds)?

• a= 5.67

  b= 6.78

  c= 4.38

• a= -5.4

  b= 7.55

  c= 4.23

• a= -0.05

  b= 0.67

  c= 4.44

• a= -3.28

  b= 6.24

  c= - 8.82

What should you do first in solving this equation?
x² + 6x - 13 = 3

• Get factored form
• Write down: a=1, b=6, c=-13
• Make it equal 0 by subtracting 3 on each side
• Type it all in a calculator.
