Is y equals 3x plus 1 and -2x2 a function?
No.
How do you write y equals 2xsquared plus 4x-7 in function notation?
f(x) = 2x2 + 4x - 7
How do you write the function y equals 2 parenthese X-1 parenthese squared plus 3 in standard notation?
y = 2(x - 1)2 + 3 y = 2(x - 1)(x - 1) + 3 y = 2(x2 - 2x + 1) + 3 y = 2x2 - 4x + 2 + 3 y = 2x2 - 4x + 5
What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
How do you find maximum or minimum of a function?
y=2x2-3x2-12x+5=0
Is y equals 3x plus 1 and -2x2 a function?
No.

How do you write the function y equals 2 parenthese X-1 parenthese squared plus 3 in standard notation?
y = 2(x - 1)2 + 3 y = 2(x - 1)(x - 1) + 3 y = 2(x2 - 2x + 1) + 3 y = 2x2 - 4x + 2 + 3 y = 2x2 - 4x + 5
What is the minimum value of the equation y equals 2x2 plus 5?
y=2x2+5. Plug in 0 for x, and you get y=2(0)^2 +5 =0+5=5. 5 is the minimum value for y.
What are the roots of the quadratic equation y equals 2x2 plus 3x-20?
2x2 + 3x - 20 = (x + 4)(2x - 5).
How do you find maximum or minimum of a function?
y=2x2-3x2-12x+5=0
What is the vertex of the parabola y-2x2-4x 4?
Assuming the missing symbol there is an equals sign, then we have: y - 2x2 - 4x = 4 We can find it's vertex very easily by solving for y, and finding where it's derivative equals zero: y = 2x2 + 4x + 4 y' = 4x + 4 0 = 4x + 4 x = -1 So the vertex occurs Where x = -1. Now we can plug that back into the original equation to find y: y = 2x2 + 4x + 4 y = 2 - 4 + 4 y = 2 So the vertex is at the point (-1, 2)
Relation is a function y equals -8?
determine whether each relation is a function y equals -8
Is x equals y a function?
y = x This is a line and a function. Function values are y values.
What best describes the function below fx equals 2x2-3x plus 1?
B- It is a many-to-one function
What quadratic function would be used to solve -2x2 plus 9x equals 12?
-2x2 + 9x - 12 = 0Then apply the quadratic formula.
Which is the vertex for y equals 2x - 7?
-5
