Please help me thank you

Answer 1

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.
