What is the rule if the input is 6 and the output is 4?
There are infinitely many possible answers: Rule I: Output = 4 (whatever the input, the output is 4). Rule 2: Output = Input - 2 Rule 3: Output = Input/2 + 1 Rule 4: Output = (Input/3)2
What is the function rule for input -2 output 13?
There are many functions where if your input is -2 the output is 13. The simplest is probably just adding 15. You could also square -2 (to get 4) and then add 9.
How do you write a function rule relating to x and y?
Y is the output of x, which is the input. So y= x + 2, y is the result of x + 2. Y is the dependent variable, and x is the independent constant.
What is the rule for this input - output table 6 in 4 out?
There are an infinite possible answer. Among the simpler ones is: Output = Input - 2
What is a zero of a function?
Assuming the polynomial is written in terms of "x": It means, what value must "x" have, for the polynomial to evaluate to zero? For example: f(x) = x2 - 5x + 6 has zeros for x = 2, and x = 3. That means that if you replace each "x" in the polynomial with 2, for example, the polynomial evaluates to zero.
What is the output value for y in the y equals 5x plus 3 function when the input value of x equals 2?
y = 5x + 3When x=2,y = 5(2) + 3 = 10 + 3 = 13
What is the rule if the input is 6 and the output is 4?
There are infinitely many possible answers: Rule I: Output = 4 (whatever the input, the output is 4). Rule 2: Output = Input - 2 Rule 3: Output = Input/2 + 1 Rule 4: Output = (Input/3)2
What is the function rule for input -2 output 13?
There are many functions where if your input is -2 the output is 13. The simplest is probably just adding 15. You could also square -2 (to get 4) and then add 9.
How do you find the numbers x-intercepts of function y equals 5x'2?
5x²=0 X=0 the function y=5x² only intercepts x when x = 0
What is the output value if the input value is 4?
Anything you like - it depends on the function that relates the output to the input.
If a function rule is 2x - 3 what is the output for 3?
Where Y = 2x-3, the output for x = 3 is Y = 3. 2x - 3 = 2(3)-3 = 6-3 = 3
How do you rewrite this equation so that y is a function of x 1 plus 7y equals 5x-2?
1 + 7y = 5x - 2 7y = 5x - 3 - 5x = - 7y - 3 x = 7/5y + 3/5 ---------------------
Is f(x)=5x^3-2 a one to one function?
Yes
What is the period of the function sin-5x?
It 2*pi/5 radians or 72 degrees.
Suppose you graph y equals 5x - 4 Which function can you graph to increase the y-intercept by 6 but leave the slope unchanged?
y = 5x + 2
How do you write a function rule relating to x and y?
Y is the output of x, which is the input. So y= x + 2, y is the result of x + 2. Y is the dependent variable, and x is the independent constant.
How do you rewrite an equation in function form?
lets say you have to write 5x+6y=-12 in function form. when you are writing an equation in function form, you usually solve for f(x) or g(x), but in this case, y is the same as f(x) or g(x). so to write 5x+6y=-12 in function form, you do this: 5x+6y=-12 6y= -5x -12 subtract 5x from both sides y= -5/6x -2 divide both sides by 6
