According to hooke's law, the force required to compress or stretch a spring from an equilibrium position is given by f(x)=kx, for some constant k. the value of k (measured in force units per unit length) depends on the physical characteristics of the spring. the constant k is called the spring constant and is always positive.

f(2x−x2)=−3x2+6x−1

step-by-step explanation:

set up the composite function and evaluate.

f(2x−x2)=−3x2+6x−1

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2
