Given the function f(x) = - 2x , find the value of f(–1). **Weegy:** f(-1) = (-1)^2 - 2(-1) = 3
f(1) = 1^2 - 2(1) = -1 (More)

When f(x) = - 2x , the value of f(–1) is 2.

f(-1) = -2*(-1) = 2.

f(-1) = -2*(-1) = 2.

In the form, y = mx + b, m stands for the slope and b stands for the y-intercept; therefore, in the equation y = 2x + 1,

Slope: 2

y-intercept: 1
