  • What is the value of a, b, and c of : f(x) = -x^2+3x-4
    a = -1, b = 3,c = -4
  • What is the constant in the given function: f(x) = -x^2 + 7x - 10?
    -10
  • True or False: Smaller values of a will make the parabola narrower.
    False
  • Solve for the discriminant f(x) = x^2 +5x + 2.
    17
  • Solve for the discriminant -2x^2 - x - 1 = 0
    -7
  • True or False: The function f(x) = x+5 is a quadratic function.
    False
  • When a<0, so the graph of the function will have .... point
    maximum
  • How many roots are there in the function f(x) = -x^2-6x - 9?
    One real root
  • what is the formula to find the discriminant of a quadratic function?
    d = b^2 - 4ac
  • True or False: The axis of symmetry is a line that passes through the vertex of the parabola and making two symmetrical shapes.
    True
  • True or False: The value of a in the given graph is greater than 0 and the d > 0.
    True
  • Solve for the discriminant 5b^2 + b - 2 = 0.
    41
  • What is the value that affects the opening of the graph?
    a
  • What is the discriminant based on the given graph?
    d = 0
  • When a>0, so the graph of the function will have .... point.
    minimum
  • From the graph, we know that the quadratic function has ... (value of a and D)
    a > 0 (because the graph has a minimum point), D < 0 (because there is no x - intercept)
  • What is the vertex of the function?
    (3,1)
