\lim_{x \to 4} f(x)=x^2+3x-1
just subsitute
f(4)=4²+3(4)-1
f(4)=16+12-1
f(4)=28-1
f(4)=27

it approaches 27 as x approaches 4

which of the following is the correct classification for triangle WXY given W(-7,1), X(0,-4) and Y(2,3)?
spin [16.1K]

Answer:

Scalene triangle

Step-by-step explanation:

Coordinates of the vertices of the triangle are,

W(-7, 1), X(0, -4) and Y(2, 3)

We will use the formula to get the distance between two points.

d = \sqrt{(y_2-y_1)^2+(x_2-x_1)^2}

WX = \sqrt{(-4-1)^2+(0+7)^2}

      = \sqrt{74}

WY = \sqrt{(1-3)^2+(-7-2)^2}

      = \sqrt{85}

XY = \sqrt{(3+4)^2+(2-0)^2}

     = \sqrt{49+4}

     = \sqrt{53}

Since, measures of all three sides of the triangle are not equal, given triangle will be a scalene triangle.
