f(x) = 7x^2 - 6x + 1

Question

Calculate the following values:

f(-2) =

f(-1) =

f(0) =

f(1) =

f(2) =

Answer 1

f(-2) means that x in the equation of the function equals (-2)

So, let's substitute:

f(-2) = 7 ^. (-2)² - 6 ^. (-2) + 1 = 7 ^. 4 - (-12) +1 = 28 + 12 + 1 = 41

f(-1) = 7 ^. (-1)² - 6 ^. (-1) + 1 = 7 ^. 1 - (-6) +1 = 7 + 6 + 1 = 14

f(0) = 7 ^. (0)² - 6 ^. (0) + 1 = 7 ^. 0 - (0) +1 = 7 - 0 + 1 = 1

f(1) = 7 ^. (1)² - 6 ^. (1) + 1 = 7 ^. 1 - 6 +1 = 7 - 6 + 1 = 2

f(2) = 7 ^. (2)² - 6 ^. (2) + 1 = 7 ^. 4 - 12 +1 = 28 - 12 + 1 = 17
