As is the case for any polynomial, the domain of this one is (-infinity, +infinity).
To find the range, we need to determine the minimum value that f(x) can have. The coefficients here are a=2, b=6 and c = 2,
The x-coordinate of the vertex is x = -b/(2a), which here is x = -6/4 = -3/2.
Evaluate the function at x = 3/2 to find the y-coordinate of the vertex, which is also the smallest value the function can take on. That happens to be y = -5/2, so the range is [-5/2, infinity).
The statement "That does not extend in both directions." will make the definition, precise.
Kevin's line segment definition is correct.
However, the end points in a line segment implies that the line segment does not extend past its two end points.
So, to make it precise;
Kevin needs to include that the line segment does not extend in both directions, in the definition.
Hence, option (c) is correct.

Answer:
19
Step-by-step explanation:
The triangle is an isosceles and so angle SRT and angle STR are equal
also:
Angle SRT and angle STU are supplementary so their sum is equal to 180
7x + 2x + 9 = 180 add like terms
9x + 9 = 180 subtract 9 from both sides
9x = 171 divide both sides by 9
x = 19
3^3. if you're simplifying then you keep the base the smae but add the exponents since you are "multiplying" the bases
