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
If y equals 5x - 2 were changed to y equals x - 2 how would the graph of the new function compare with the first one?
The graphs of y = 5x - 2 and y = x - 2 will have different slopes but with the same y intercepts.
How do you solve 5x-2 3x-6?
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
Rewrite the equation 5x-2y0 in slope-intercept form?
5x - 2y = 05x - 5x - 2y = 0 - 5x-2y = - 5x(-2y)/-2 = (-5x)/-2y = (5/2)x where the slope is 5/2 and the y-intercept is 0.
What is 2x(5x-2)?
It is: 10x^2 -4x = 2x(5x-2)
Rewrite fx equals 5x plus 2?
f(x)=5x+2
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
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 output for -2 if the function rule is 5x - 3?
5*(-2) - 3 = -10 - 3 = -13
What is the period of the function sin-5x?
It 2*pi/5 radians or 72 degrees.
What is the range of the function fx 3.2x for the domain -4 -2 0 2 4?
It is -12.8, -6.4, 0, 6.4 and 12.8
What is the inverse function of f fx equals sqrt2x-1?
3
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 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
What is the slope and y-intercept of 5x plus 2y plus 3 equals 0?
Put in point slope/function form. 5X + 2Y + 3 = 0 5X + 2Y = - 3 2Y = - 5X - 3 Y = - 5/2X - 3/2 slope = - 5/2 ---------------- Y intercept = - 3/2 -------------------------
What is the value of fx at x-2?
That depends what the function is! Just replace every occurrence of "x" by "x-2", and do any required simplifications.
