f(x)= -4x^2+10x-8 what is the value of the discriminant of f how many distinct real number zeros does f have
Mazyrski [523]

Answer:

Step-by-step explanation:

The function is f(x) = -4x²+10x-8

Let Δ be our the dicriminant

  • Δ= b²-4ac
  • b = 10
  • a = -4
  • c = -8
  • Δ = 10²-4*(-4)(-8)
  • Δ = 100-128
  • Δ = -28

The value of the discriminant is -28 and since it is negative this function has no real zeroes
