I have no idea how to explain it so you would understand it, but just know that you need to have factors of the third number (40(with no variables)) be equal to the second number (-14x(Which only has a variable (not squared)))
Therefore a factor would be -10 and -4, since -10*-4=40 and -10+(-4)= -14
With these two numbers you can set it up so that it's like this;
(x-10)(x-4)
Having this, you now have 2 equations;
x-10 = 0
and
x-4=0 (Don't ask why)
So now you solve for x, making it 10 or 4
Answer:
A. (-∞, ∞)
Step-by-step explanation:
f circle g (x) is another way of expressing f(g(x)). Basically, we have to plug g(x) into f(x) wherever we see x's.
f(x) = x^2 - 1
f(x) = (2x-3)^2 - 1
Now find the domain. I think the easiest way to do this is to graph it. I've attached the graph. You can also do it algebraically by thinking about it: it's a positive parabola (+x^2) and its minimum is -1, so its range will not be all real numbers, but its domain will certainly be. (The range would be answer choice B!)
Domain = (-∞, ∞)
Answer:
Mode :6 Range :5
<em>Step-by-step explanation</em>
<em>To find the mode look for the number that is repeated the most times. And to find the range subtract the greatest number with the smallest number. Hope this helped :) </em>
