y is greater than 0
You pass arguments to functions because that is how you tell the function what you want it to do. If you had, for instance, a function that calculated the square root of something, you would pass that something as an argument, such as a = sqrt (b). In this case sqrt is the function name, b is passed as its argument, and the return value is assigned to a.
Y = 1/X2 ==============Can it pass the line test? * * * * * That is not the inverse, but the reciprocal. Not the same thing! The inverse is y = sqrt(x). Onless the range is resticted, the mapping is one-to-many and so not a function.
sqrt(x) Range: {0,infinity)
sin(-120)=sqrt(3)/2 cos(-120)=-1/2 tan(-120)=-sqrt(3) csc(-120)=2/sqrt(3) sec(-120)=-2 cot(-120)=-1/sqrt(3)
sqrt(700x4) = sqrt(2800) = 52.92 approx.
x=y^2 may be written as y=+/-sqrt(x) The domain for sqrt(x) is [0, infinity). The range is also [0, infinity) However, y=+/-sqrt(x) is not a function, because one element in the domain has two values in the range set.
No, without any restriction in the range, it is not a function. If it were a function, each value of x could have at most one value of y.However, suppose x = 0. Then y = sqrt(0 + 27) = sqrt(27) = -3*sqrt(3) and + 3*sqrt(3) that is, there are two possible values of y for x = 0. The same is true for each value of x > -27.

The square root function is SQRT, like this:=SQRT(value)To square a number, either multiply it by itself, using the POWER function or the power operator. If you had a value in cell A2, all of the following would do the same thing:=A2*A2=POWER(A2,2)=A2^2
square root of the argument
The function sec(x) is the secant function. It is related to the other functions by the expression 1/cos(x). It is not the inverse cosine or arccosine, it is one over the cosine function. Ex. cos(pi/4)= sqrt(2)/2 therefore secant is sec(pi/4)= 1/sqrt(2)/2 or 2/sqrt(2).
√75 = √3*25 which would give you 75 so it would be 5√3
it is sqrt in header math.h
The square root function is one of the most common radical functions, where its graph looks similar to a logarithmic function. Its parent function will be the most fundamental form of the function and represented by the equation, y =sqrt {x}.
As long as the line represented on the graph has no vertical segments then it may be represented by a function. * * * * * That is not enough. y = sqrt(x) has no vertical segments but it is not a function in the mathematical sense. A function cannot map an x value to more than one y value. Clearly, the above function maps x to -sqrt(x) and +sqrt(x) and so is not a function. However, there no vertical segment. No matter how close you get to x = 0, there is still a curve and the segment is not vertical.
