Which quadratic function is the standard form of the equation shown?

f(x) = x + 8 + 2x + 5x2

f(x) = 8 + 5x2 + 2x + x
f(x) = x + 2x + 5x2 + 8
f(x) = 8 + 3x + 5x2
f(x) = 5x2 + 3x + 8

Combine like terms: x + 2x = 3x, and 5x2 = 5x^2. Writing highest power first gives

f(x) = 5x^2 + 3x + 8.

(That’s the last option.)
