How do you to sketch a graph of a function whose domain is in the closed interval 0-4 and whose range is the set of two numbers 2 and 3?
Find the domain of the relation then draw the graph.
Inverse function 2x plus 4?
y=2x+4 --> x=2y+4 ==> y=(x-4)/2
What is the domain range asymptote and intercept of the equation y equals 4 times 2 exponent x?
y = 4(2x) is an exponential function. Domain: (-∞, ∞) Range: (0, ∞) Horizontal asymptote: x-axis or y = 0 The graph cuts the y-axis at (0, 4)
What is the inverse function of y -2 3x plus 2?
If you mean: y-2 = 3x+2 then as a straight line equation it is y = 3x+4
Is x equals the square root of y-4 a function?
The square root operation is not a function because for each value of y there can be 2 values of x - the principal square root and its negative. This can only be rectified by limiting the range of the opearation to the principal or positive square root. Furthermore, it also depends on the domain of the function. If y<4 then the square root is not defined within Real numbers. So, for y ≥ 4, x = +sqrt(y-4) is a function.
