y ≥ 11
x2+2x+1=y or y=x2 In this function the domain is x equals real values and the range is y equals all real values provided y is more than or equal to zero.
The domain of y = x2 is [0,+infinity]
if y = x2 + 1 Then the minimum value of y is 1, which happens at the point (0, 1). It lies in the domain of real numbers. i.e. {y | y ≥ 1, y ∈ ℝ}
If you mean y = x2, then yes, it is nonlinear.
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
No translation will invert a quadratic graph.
the graph is moved down 6 units
y = 4x-3
Y = X2 forms a parabola
Yes. Think of y as being a function of x. y = f(x) = x2 + 1
y = x2 + 4 The graph is a parabola, with its nose at y=4 on the y-axis, and opening upward.
