Which of the quadratic functions has the narrowest graph?
y = -10x2
y
y=8
y = -0.972

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1  

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
