Research studies show that the relationship between the tire pressure of a vehicle's tires and the life of the tires is quadratic. The following table shows data for the tire pressure of a car's tires (in pounds per square inch) and its
average tire life (in thousands of miles).

Use a graphing or online regression calculator to find the quadratic function of best fit for this set of data. Then, predict
the tire life for this vehicle's tires given that the tire pressure is maintained at 30 psi (pounds per square inch).
47,800 miles
48,800 miles
50,800 miles
51,800 miles

the answer is 62

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu

3x^3-2x^2+4x-3= -3

x^2+3x+3= 3

-3÷3= -1
