Evaluate ƒ (-3) for ƒ (x) = - 5x2 + 2x - 1.

Evaluate ƒ (-3) for ƒ (x) = - 5x2 + 2x - 1.

ƒ (x) = - 5x2 + 2x - 1

First, Substitute x by - 3 in the formula of the function and calculate as follows.

ƒ (-3) = - 5x2 + 2x - 1

Apply the Order of Operations.

ƒ (-3) = - 5 (-3) ^2 + 2 (-3) - 1

Simplify

ƒ (-3) = - 5 (9) + 2 (-3) - 1

ƒ (-3) = - 45 - 6 - 1

ƒ (-3) = - 52

Therefore, The function of ƒ (-3) for ƒ (x) = - 5x2 + 2x - 1 is - 52
