We start by restating the problem in our own words and identifying the blanks to fill with expressions derived from f(x) = 2x^2 + 6x + 3. Compute f(-4): f(-4) = 2(-4)^2 + 6(-4) + 3 = 2(16) - 24 + 3 = 32 - 24 + 3 = 11. - Among the provided options, only the first value '11' matches this result for the blank f(-4). All other numeric strings do not equal 11, so they are incorrect for this specific blank. Compute f(-x): f(-x) = 2(-x)^2 + 6(-x) + 3......Login to view full explanation
