if a function has a unique y value for each x value the function is one to one.
In Roman numerals the symbol "X" means 10.
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
There's no way we can figure that out until you tell us how 'x' and 'y' are related to each other. That kind of information is called an "equation".
y is a function of x iffor each value of x (in the domain) there is a value of y, andfor each value of y (in the range) there is at most one value of x.
Any equation which maps each value of x in the domain to a value in the range is a function of x.
X is an unknown quantity. You would need the rest of the equation to figure out the value of X.
A set of ordered pairs that assign to each x-value exactly one y-value is called a function.
each time you add 1 to x the value goes up by one for example if x=2 then 5+2=7 but if you add 1 to x and x=3 then 5+3=8
It will be 16.
There are infinitely many. For each value of x there is a value of y, and there are an infinite number of values of x to start with.
Select a set of values for x. For each value calculate the value of f(x). On a graph paper, mark the points [x, f(x)].
If x equals 4 and y equals 8 to one significant figure thelowest value of x would be 3.49 (the nine is recurring and the lowest value of y would be 7.49 (the nine is recurring so the lowest over all value of the two would be 10.98 (the eight is recurring
Figure Y is circumscribed about figure X.
Replace each point with coordinates (x, y) by (-x, y).
5 significant figures Each figure that contributes to the accuracy of a value is considered significant. So 2.9979 has 5 significant figures. The 10^8 does not contribute to the accuracy as it simply indicates the number of trailing zeroes (i.e. 299,790,000) that are simply a result of rounding from the actual value (299,792,458)
y = x - 3 is a linear function where for each x-value we find one and only one y-value.
That's a normal function. It means that it passes the vertical line test. A function where there is only one y-value for each x-value and only one x-value for each y-value is called a one-to-one function. The inverse of a one-to-one function is also a function.many-to-one function. ~APEX
you times that number by the one replaced with x
Set up the equation: x + 19 = 76 (then subtract 19 from each side to find the value of x) x = 57
y2 + x = 7 : this can be written as y2 = 7 - x or x = 7 - y2. There is not a specific solution to this identity. For each different value assigned to x then a different value is generated for y. Or, it can be viewed that for each different value assigned to y then a different value is generated for x. This expression is therefore a function.
Starting from the right, and working left - each digit is 8 times the value of the preceding one. So - in this example...The figure 3 remains the same.The figure 4 is 8 x 4... 32The figure 2 is 8 x 8 x 2... 128So... 3+32+128=163
The only function that can be symmetric about the x-axis is the x-axis itself. For each value of x a function, f(x), can have at most one value for f(x). Otherwise it is a mapping or relationship but not a function.
