Linear functions never have maxima and minima, so a) is discarded.

In the options there are quadratic functions, they can present either a maximum or a minimum.

You can know instantly by seeing the sign of the variable ${x}^{2}$ , if positive the parabola opens up, then it will have a minimum, if negative the parabola opens down, having a maximum.

$\mathbb{ANSWER} \rightarrow \boxed{ \boxed{y = - {7x}^{2} - 1 }}$

Graph the line giving one point and the slope. 2x-6y=12

koban [17]

Y = mx + c

this is the equation of line and here m is the slope

so, 2x-6y =12 can be changed into standard format

y = 2x/6 - 12/6
y=x/3 +(-2)

so, m = 1/3 , so slope will be 1/3

hope it helped :)

Answer:

Saw this question before. The answer is Anita' square.

Square has only four sides while the others more than four so make sense for the square to have longer sides
