Is y equals 3x plus 1 and -2x2 a function?
No.
Y equals 4x plus 3 is this a one to one function or an onto function and does it have an inverse function?
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
What type of function is y equals x plus 1?
It is a linear function. That is to say, it is a function representing a straight line in the coordinate plane.
What is 1 plus 1 plus 1 plus 1-4 plus g equals?
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
Cos x equals -cos x plus 1?
No, but cos(-x) = cos(x), because the cosine function is an even function.
Is y equals 3x plus 1 and -2x2 a function?
No.
What is the range of the function y equals x2 plus 1?
The answer depends on the domain. If the domain is the whole of the real numbers, the range in y ≥ 1. However, you can choose to have the domain as [1, 2] in which case the range will be [2, 5]. If you choose another domain you will get another range.
Does the equation y equals 2x plus 1 represent a function?
The [ 2x + 1 ] represents a function of 'y' .
Y equals 4x plus 3 is this a one to one function or an onto function and does it have an inverse function?
Assuming the domain and range are both the real numbers (or rationals): Yes, it is 1 to 1 Yes, it is onto and the inverse is x = (y-3)/4
What type of function is y equals x plus 1?
It is a linear function. That is to say, it is a function representing a straight line in the coordinate plane.
What best describes the function below fx equals 2x2-3x plus 1?
B- It is a many-to-one function
Is y equals x2 plus 1 a function?
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
What is the range of sin -1?
If you mean the arcsin function then the range is the whole of the real numbers - from "minus infinity" to "plus infinity". If you mean the cosecant function, the answer is the whole of the real numbers excluding (-1, 1).
Does 1 plus 1 plus 1 plus 1 equals 3.8?
No...it equals 4...
What is 1 plus 1 plus 1 plus 1-4 plus g equals?
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
Is y equals 5x plus 1 a function?
Y = 5X + 1 Is a line and should pass the vertical line test for functions, so this is a function.
What is 4 plus 1 plus 4 plus 77685769844446473 plus 3 plus 8 plus 1 plus 23122312 plus 6 plus 1 equals 2 plus 9870998342523322424 plus 4?
4+1=5. Plus 4 equals 9. Plus 77685769844446473 equals 77685769844446482. Plus 3 equals 77685769844446485. Plus 8 equals 77685769844446493. Plus 1 equals 77685769844446494. Plus 9870998342523322424 equals 1064785604097768918. Plus 4 equals 1064785604097768922.
