Mabel was asked whether the following equation is an identity: (4x - 3)(x - 2)2 = 4x3 – 19x2 + 4x - 12 - She performed the following steps: (4x - 3)(x - 2)2 - - Step 1 (4x – 3)(x - 2)(x - 2) Step (4x - 3)(x2 - 2x - 2x + 4) II Step 3 = (4x – 3)(x2 - 4x + 4) Step 4 423 – 16x2 + 16x – 3.xº - 12x – 12 Step 5 4x3 – 19x2 + 4x – 12 For this reason. Mabel stated that the equation is a true identity, Fit

no

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

no
