Step-by-step explanation:
The standard form of a quadratic equation is f(x) = ax^2<span> + bx + c. Looking at the given choices:
</span><span>A. f(x) = −8x^3 − 16x^2 − 4x
B. f(x) = x^2 + 2x − 5
C. f(x) = 1
D. f(x) = 0x^2 − 9x + 7
Among the choices, the only equation that follows the standard form is B.</span>
Answer:
what's the Question???
Step-by-step explanation:
Answer: Looks like choice B would be the best description of an output.. Usually, output refers to the dependent value of a function rule. It is also correct that the y coordinate of ordered pairs, graphed points, and in a function table.

Answer:
C. 12cm
Step-by-step explanation:
The equation for the perimeter of the rectangle is ...
P = 2(L+W)
34 = 2(n +m)
Solving for m, we get
m = 17 -n . . . . . . . divide by 2, subtract n
__
The Pythagorean theorem gives the relationship between the sides and the hypotenuse
m^2 +n^2 = (n+1)^2
(17 -n)^2 +n^2 = (n +1)^2 . . . . . . substitute for m
289 -34n +n^2 +n^2 = n^2 +2n +1 . . . . eliminate parentheses
n^2 -36n +288 = 0 . . . . . . . put in standard form
(n -12)(n -24) = 0 . . . . . . . . . factor
n = 12 . . . . . . . . . . n=24 is an extraneous solution here
The value of n is 12 cm.
