Because in the function f(x) all you do is plug in the value that is given...7
2*7-5=14-5=9
Your answer is 9.
The answer is B not any other mostly because you need to
subtract both equations to remove the variable.
y=-2x^2-8x-4
-2x^2-8x=4
divide by negative 2
x^2+4x=-2
complete the square
(x+2)^2=-2+4
(x+2)^2=2
x+2=±
x=-2±
nearest hundreths,
x=-0.59
x=-3.41
