Wooooo hooooo!!!!!!!!!!!!!
Domain:
This function is a polynomial, i.e. a sum of powers of a variables, each with its coefficient. Polynomials are defined for every possible value of the variable, so the domain is the whole real number set: 
Range:
A polynomial of degree 2 represents a parabola. Since the leading coefficients, i.e. the coefficient of the term with highest degree, is positive (in this case, it's 3), the parabola is concave up. It means that it has a minimum, and it's unbounded from above. So, the range is something like 
. To find the minimum, let's start with the "standard" parabola 
, and transform it to the one of this exercise. has minimum 0, and thus its range is 
. When you multiply it times three, its shape narrows, but the range wont change: 
. Finally, when you subtract 5, you shift everythin down 5 units. This transformation affects the range, since you have

To compute 
, simply plug 
in the formula:
Numbers associated with 43:
We want to see which x value we must choose to get a y value of 43. So, the equation is
I think the answer it’s 15 in not 100% sure tho
When you name two congruent triangles with the letters of the vertices, you have to keep the order of the corresponding vertices. That means, that when you say triangle ABC is congruent to DEF, the corresponding congruent angles are A = D, B = E, and C = F. regarding the sides, segment AB = segment DE, segment BC = segment EF, and segment CA = segment FD. Then, the answer is that, of the four options,<span> the one that is not true is the option b, because as we already said the corresponding equal angle C is F, not E.</span>
If you would like to know how far did Mackenzie run in one hour, you can calculate this using the following steps:
26 1/5 = 131/5 miles ... 5 4/5 = 29/5 hoursx miles = ? ... 1 hour
131/5 * 1 = 29/5 * x131/5 = 29/5 * xx = 131/5 * 5/29x = 131/29x = 4 15/29 miles
The correct result would be 4 15/29 miles.
Hope this helps :D
