all real numbers
The graph is a circle with a radius of 6, centered at the origin
x-7
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
all real numbers
Y = x squared -4x plus 3 is an equation of a function. It is neither called a domain nor a range.
x(x + 9)(x + 1)
The graph is a circle with a radius of 6, centered at the origin
x-7
The answer depends on the domain for x. For example, if the domain is x = 7, then the range is 55. If the domain is all Real numbers, then the range is y >= 6.
By factoring I get x-3 divided by x+3
They are terms of an expression because without an equality sign it is not an equation.
x2 - 9x + 20 = (x - 4)( x - 5)
x2 + 9x + 20 = 0 ∴(x + 4)(x + 5) = 0 ∴x ∈ {-5, -4}
x[x+1] squared Simplified is, to my knowledge, x squared plus ( x + 1) squared
x2 + 8x - 9 = (x + 9)(x - 1)
