Answer:
A) The model exists: f(x) = -3x^2 +4x -4
Step-by-step explanation:
A quadratic model will always exist for 3 given points, provided they are not on a line. In that case, a linear model is appropriate.
Here, the slope between -1 and 0 is positive, and the slope between 0 and 3 is negative. Thus, we know these points are not collinear, and a model must exist.
The model is most easily found using a quadratic regression tool. Such is shown in the attachment. It tells us that ...
f(x) = -3x^2 +4x -4
Answer:
x = 4 + √ 38
Step-by-step explanation:
Y is the easiest to fix because it has no coefficient, and is therefore the easiest to set on the other side of the equation by itself
19+ 17 = 36
right angle = 90°
90 - 36 = 54
