Review how to figure out how to find the equation that represents the relationship between the x and y variables given in a function table This video revieTable A Input Output 3 1 3 4 2 3 Table B Input Output 2 7 5 6 2 9 Table C Input Output 1 5 7 2 7 3 Table D Input Output 3 4 1 5 8 53) which values for x and y will make Math Which of the tables represents a function?
Domain and range The domain and range of a function is all the possible values of the independent variable, x, for which y is defined The range of a function is all the possible values of the dependent variable y The example below shows two different ways that a function can be represented as a function table, and as a set of coordinatesIf the table has a linear function rule, y = y y = y for the corresponding x x value, x = 0 x = 0 This check passes since y = 5 y = − 5 and y = 5 y = − 5 5 = 5 − 5 = − 5 Calculate the value of y y when a = 4 a = 4, b = 5 b = − 5, and x = 1 x = 1 Tap for more steps Multiply 4 4 by 1 1Given random variables,, , that are defined on a probability space, the joint probability distribution for ,, is a probability distribution that gives the probability that each of ,, falls in any particular range or discrete set of values specified for that variable In the case of only two random variables, this is called a bivariate distribution, but the concept generalizes to any

y = − 3 Finally, for 1 f (x) = − 1 2x −3 f (x) = − 1 2(1) − 3 Solve for y y = − 7 2 or y = − 35 Your final results in a table of values would look like this and if your curious, the graph would look like this graph { ( (1/2)x)3 5666, 4334, 402, 098}Exponential Function • A function in the form y = ax – Where a > 0 and a ≠ 1 – Another form is y = abx c • In this case, a is the coefficient • To graph exponential function, make a table • Initial Value – – The value of the function when x = 0 – Also the yinterceptIn the relation X is equal to Y squared plus 3 can Y be represented as a mathematical function of X so the way they've written it X is being represented as a mathematical function of Y we could even say that X as a function of Y is equal to Y squared plus 3 now let's see if we can do it the other way around if we can represent Y as a function of X so one way you could think about it is you could essentially try to solve for y here so let's do that so I have X is equal to Y squared plus 3
3) which values for x and y will make Calculus Consider the function f(x)=sin(5x)/xBased on the quadratic function shown in the table below, which of the following is the range of this function?In the following table is why a function of X in order for y to be a function of X for any X that we input into our little function box so let's say this is y as a function of X it needs to spit out at an only only one value of y if it spit out multiple values of Y then it might be a relationship but it's not going to be a function so this is a function this is a function if we had a situation
