Using the given function below, determine if the following coordinate points area solution to the function
y = 3x2 + 1
(1,5) (-2,13)

see explanation

Step-by-step explanation:

To determine if the points are a solution substitute the x- coordinate into the function and if the value obtained is equal to the y- coordinate of the point then it is a solution

(1, 5)

y = 3(1)² + 1 = 3 × 1 + 1 = 3 + 1 = 4 ≠ 5 ← (1, 5) is not a solution

(- 2, 13)

y = 3(- 2)² + 1 = 3 × 4 + 1 = 12 + 1 = 13 ⇒ (- 2, 13) is a solution

hihi so drawing these 2 triangles is fairly simple. all that's left is finding the height of each one. luckily, we have a side length and an angle, so there is a trig function we can use to solve for the height. the easiest one to use would be tangent, since we have 2/3 things needed to find and the third needed is what we are solving for. tan(73°) * 30 ~= 98.13 and tan(73°) * 35 ~= 114.45
