Answer:  2 real zeros

discriminant:  b^2 - 4ac
a = 3, b = -7, and c = 4
so, (-7)^2 - 4(3)(4) = 1
Since the discriminant is positive, there are 2 real zeros, if the discriminant was negative there would be 2 complex zeros, and if the discriminant equaled 0 then there is one real answer

Answer:

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

Step-by-step explanation:

Put the value where the variable is and do the arithmetic.

Personally, I find it easier not to deal with so many minus signs. I would rewrite the function to ...

  f(x) = -(8 +x)

I find it easier to evaluate the series of argument values when they are in increasing order. This serves as a check, because we expect the function values to be in decreasing order.

f({-3, -2, 0, 2, 4}) = -(8 +{-3, -2, 0, 2, 4}) = -{5, 6, 8, 10, 12} = {-5, -6, -8, -10, -12}

  • f(4) = -12
  • f(-2) = -6
  • f(2) = -10
  • f(0) = -8
  • f(-3) = -5

_____

As always, for repetitive evaluation of the same function, a spreadsheet or graphing calculator is a handy tool.
