Answer:

y = -x +3

Step-by-step explanation:

Think about the Y= mx + b

m = -1 so it's -x

b = 3, so it's +3

y intercept goes after the slope:

Y= Mx + B

Y = -x + 3

How am I supposed to integrate this?

svlad2 [7]

$6x^2-4x+1=6\left(x-\dfrac13\right)^2+\dfrac13\ge0$

which means the parabola lies above the x-axis over its entire domain. This means the area is given by

$\displaystyle\int_{-1}^2(6x^2-4x+1)\,\mathrm dx=2x^3-x^2+x\bigg|_{x=-1}^{x=2}=10-(-5)=15$
