Function notation fx is read as?

If it were written in a book of some sort, fx or f(x) is read aloud as "f or x". "f" is a function of some variable, "x". By function it means something happens to x e.g. x2 or 3x+4.


Define one-to-one function?

the function (x),sory I can`t use the sign of the function because it is not available. the function of (x)=4x+4 is one to one function assume function(x1)= function(x2) then 4(x1)+4 =4(x2)+4 4(x1)=4(x2) (x1)=(x2) hence,the function is one to one


Use the the following functions to solve fx x2 x 1 gx 5 - 2x hx -x2 goh2?

What is nonlinear expression?

It can be thought of as a function that does not graph to a line when plotted. For example, y=4 or y=5x are linear. But y=x2 or y=x1/2 or y=ln(x) are not linear


Why are not all functions linear equations?

Linear equations can be written as y = mx + b. Any other function would be non-linear. Some linear equations are: y = 3x y = 2 y = -2x + 4 y = 3/4x - 0.3 Some non-linear functions are: f(x) = x2 y = sqrt(x) f(x) = x3 + x2 - 2


Evaluate the function fx equals -x2 plus 5 for x equals 4?

Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.


Is y equals x2 plus 4 a linear equation?

It is linear in y, quadratic in x. Generally, that would be considered a quadratic.


What are linear and nonlinear regression?

A linear equation is an equation that in math. It is a line. Liner equations have no X2. An example of a linear equation is x-2 A linear equation also equals y=mx+b. It has a slope and a y-intercept. A non-linear equation is also an equation in math. It can have and x2 and it is not a line. An example is y=x2+3x+4 Non linear equations can be quadratics, absolute value or expodentail equations.


What does non- linear function mean?

It means if you plot the function it is not on a straight line For example y = 3x + 4 is linear function y = x squared is non linear

What is another name for the root of a function?

The "root" of a function is also called the "zero" of a function. This is where the function equals zero. The function y=4-x2 has roots at x=2 and x=-2 The function y=4-x2 has zeroes at x=2 and x=-2 Those are equivalent statements.


What is the vertex of the parbola y equals x2-4x plus 12?

Y = X2 - 4X + 12 set to 0 X2 - 4X + 12 = 0 subtract 12 from each side X2 - 4X = - 12 now, take the linear term ( - 4 ), halve it, square it and add it to both sides X2 - 4X + 4 = - 12 + 4 factor the left side, gather terms on the right (X - 2)2 = - 8 add 8 to each side (X - 2)2 + 8 = 0 ------------------------ (2, 8) ------------the vertex of this function
