Given f, left bracket, x, right bracket, equals, 3, x, squared, minus, x, plus, 2f(x)=3x
2
−x+2, find f, left bracket, minus, 4, right bracketf(−4)
To find f(-4), we need to substitute -4 into the given equation for x:
f(x) = 3x^2 - x + 2f(x) = 3x - x + 2
f(-4) = 3(-4)^2 - (-4) + 2
= 3(16) + 4 + 2
= 48 + 4 + 2
= 54
Therefore, f(-4) = 54.
