Afunction f(x) is transferred from the parent function p(x) = |x| by a reflection over the x-axis, vertical stretched by a factor of 2.5 and shifted down 3 units. write the equation for the function f(x)

Which best describes the transformation that occurs in the graph? a) dilation b) reflection c) rotation d) translation

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

[10 points, algebra 2-simplifying complex fractions]according to my answer key the restrictions are -1 and 4. but why not positive 1?
