Answer:

Step-by-step explanation:

G(x) exceeds f(x) from x = 0 to x = 3.

Then we see that f(x) is 11 at x = 4 and g(x) is 10 at x = 4, so there is an intersection between these 2 points.

After this f(x) far exceeds g(x).

$x^2+7x=-12\\x^2+7x+12=0\\x^2+3x+4x+12=0\\x(x+3)+4(x+3)=0\\(x+4)(x+3)=0\\x=-4\ and \ x=-3$

If b = 3, then 3x + y = 1 and bx - y = 3 are parallel.<br> True or <br> False ...?

Ulleksa [173]

I am absolutely sure that the task <span> b = 3, then 3x + y = 1 and bx - y = 3 is NOT parallel, which means that the statement represented above is FALSE.
To make sure you can check it using : </span> $y=-3x+1

y=3x-3$ Hope now it's obvious. Regards!
