Find the y-intercepts of 16y squared equals 120x-225?
We are told: 16y2 = 120x - 225 The y-intercepts will happen where x equals zero, so we can say: 16y2 = 120(0) - 225 16y2 = -225 y2 = -225 / 16 y = √(-225 / 16) y = ±15i/4
How do you find the x and y intercepts of an equation?
Substitute zero for x to find the y-intercept, and substitute zero for y to find the x-intercept.
How do you find how many x intercepts the parabola has using the discriminant?
If the discriminant is negative, there are 0 interceptsIf the discriminant is zero, there is 1 interceptIf the discriminant is positive, there are 2 intercepts
What is the least number of intercepts for a line?
Zero
Why do you equate the equation to zero?
Not all equations are equated to zero, but usually we set a function equal to zero if we want to find its x intercepts, or where the graph of the function crosses the x axis.
How many x intercepts are in y equals 2x2 plus 4x plus 3?
None because the discriminant of this quadratic equation is less than zero.
What is the least number of intercepts for a circle?
Zero
Why is the least number of intercepts for a circle zero?

Find the x-intercepts for the parabola defined as y equals -9 x to the second power-6x plus 9 answer as two ordered pairs?
The x intercepts are when y=0. Substitute the zero in for all y and then solve. Use quadratic formula and reduce. I got (-1+/- sqrt 10)3 about .72075922 and -1.387425887
What s the x and y intercepts for 9x-2y equals 27?
An easy way to find the intercepts is to substitue zero into the other variable. y-intercept is when x=0 -2y=27 y=-27/2 y=-13 1/2 is the y-intercept. 9x=27 x=3 is the x-intercept.
What is the x-intercepts of f of x equals x plus four divided by x?
Find the x-intercepts of f(x)=(x+4)/x The instructions simply mean that you should set f(x) equal to 0. To get the answer, you must set the numerator equal to zero, so x+4=0. Then x=-4 is the answer.
How do you find the y intercept for x equals 2y2 plus 3y plus 1?
The y-intercept is the place (or places) where x=0 . So if 'x' is 2y2+3y+1 , then all you have to do is find places where 2y2+3y+1 is zero, and those are your y-intercepts.
