SOLUTION: how do you find the domain and range of these …
sinx goes back and forth between -1 and 1, so the domain is all real numbers (there is no real number that you cannot take the sine of) and the range is all real numbers between -1 and 1, inclusive. The domain of 2sinx is the same as the domain of sinx, but every y value of 2sinx is stretchedtwice as far away from the x-axis as that of sinx so ...

SOLUTION: Quadratic Function Find the a: vertex b: domain c: …
You can put this solution on YOUR website! Quadratic Function Find the a: vertex b: domain c: range of f(x) = -2x^2 - 4x +3
SOLUTION: Find the domain and range of the INVERSE of the …
Now, the Range is the set of all resulting y values. Because y = a square root, y cannot be negative. Also, the values of y increase without bound, so the Range is What we just determined was the DOMAIN and RANGE of the FUNCTION. Now, for the INVERSE FUNCTION, DOMAIN and RANGE are REVERSED! For the INVERSE FUNCTION, Domain is or [0, inf),
SOLUTION: find the range and domain. f(x)=1/x+2 - Algebra …
Now to find the range, notice that there isn't an x term in the numerator. So if , there isn't an x value that will satisfy the equation. So in other words, will never be equal to zero. So this means we must take 0 out of our range. So our range is: which in plain English reads: y is the set of all real numbers except
I need to know the X and Y Intercepts - Algebra Homework Help
You can put this solution on YOUR website! Y-intercepts. Point(s) where a graph intersects the y-axis. Points on the y-axis have an x coordinate that is zero so to find y intercepts, make x zero and use the equation to figure out y: So the y-intercept is (0, -3) X-intercepts. Point(s) where a graph intersects the x-axis.
what is the domain and range? - Algebra Homework Help
You can put this solution on YOUR website! ax^2+bx+c x^2-4x+3 (x-3)(x-1)=0 x=3, x=1 when y=0 The graph of the parabola has a minimum because a is positive. (3+1)/2=2 so y will be at a minimum when x=2 f(x)=y=2^2-(4*2)+3 =4-8+3 =-1 The domain of x is all real numbers. The range of y is -1 to infinity.
SOLUTION: How do I find the variance and the standard deviation …
Question 1036440: How do I find the variance and the standard deviation in this problem? I know the range is 11 and the mean is 16.2.. The ages (in years) of a random sample of shoppers at a gaming store are shown. determine the range, mean, variance, and standard deviation of the sample data set. 12, 17, 23, 13, 14, 17, 20, 16, 15, 15
