How do you find the range and domain of a graph function?
Assuming the standard x and y axes, the range is the maximum value of y minus minimum value of y; and the domain is the maximum value of x minus minimum value of x.
Is x plus y equals 4 a function?
Yes.
Factorise x2 minus y2 plus 9x minus 9y?
x2 - y2 + 9x - 9y =(x2 + 9x) - (y2 + 9y) =x(x + 9) - y(y + 9)================================Another way to go after it:x2 - y2 + 9x - 9y =(x2 - y2) + 9x - 9y =(x + y) (x - y) + 9 (x - y) =(x + y + 9) (x - y)
2x plus 3y equals 13 3x minus y equals 3 x equals?
2x+3y=13 3x-y=3 x=2
What is the factorization of f(x)6x plus 4?
f(x) or y = 6x + 4Well, y= mx+ b This function is simplified already.
Given the function y equals minus 3 divided by 4 x square plus 15 what is the value of y when x equal minus 3?
33/4
If x squared minus y squared equals 10 and x plus y equals 5 what is x minus y?
2
What is the derivative of x minus y divided by x plus y?
m
How do you factor x squared minus 2 x y plus y squared?
it is (x-y)(x-y) :)
What is x if x minus 20 percent of x equals y?
x is y plus 25% of y.
How do you find the y intercept of p of x equals x to the fourth plus 2x cubed plus x squared plus 8x minus 12?
p(x) = x4 + 2x3 + x2 + 8x - 12When you go to graph this function, you make 'y' = p(x) .At the y-intercept, 'x' is zero.There, y = -12 .
If X plus Y equals 15 and X minus Y equals 5 what is X times Y minus X plus Y?
Your question is like this:X+Y=15, X-Y=5, (X x Y)-X+Y= ?According to my calculations, X=10 and Y=5, therefore (X x Y)-X+Y= 45.
What is a negative minus a negative?
A negative minus a negative turns the latter into a plus positive,for example -6 minus -3 would be :-6 ++ 3 = -3A minus negative always turns into a plus positive...To get more Specific:Suppose x and y are two POSITIVE numbers so that -x and -y are negative. Then a negative minus a negative = (-x) - (-y) = -x +yIf x > y the answer is negativeIf x = y the answer is zeroIf x < y the answer is positive
Is this equation a function y equals 3squared plus 2x minus 3 is this a function?
You can tell if an equation is a function if for any x value that you put into the function, you get only one y value. The equation you asked about is the equation of a line. It is a function.
How do you solve -x plus y equals 1 and -2 plus y equals -2 by substitution?
-x+y = 1 -2+y = -2 y = 1+x y = -2+2 => y = 0 By sustituting the values of x and y can be found x = -1 and y = 0 Remember that a minus from a minus is equal to a plus. So - -1+0 = 1
Find turning points for the function y equals x cubed divided by 3 minus x squared minus 3x plus 5?
Locate the turning point(s) for the following functions. (a) y=x3-x2 -3x + 5 3
Is x squared plus 5y minus x equals 7 a function?
No. It is an equation. A function would link the variable x to another variable - possibly denoted by y. It is a relationship between two (or more) variables.
