The function y = (A-2) x-3a-1 is known. When the value range of independent variable x is 3 ≤ x ≤ 5 Then. Y can reach both the value greater than 5 and the value less than 3. Find the value range of real number a

The function y = (A-2) x-3a-1 is known. When the value range of independent variable x is 3 ≤ x ≤ 5 Then. Y can reach both the value greater than 5 and the value less than 3. Find the value range of real number a

If a > 2, the function is an increasing function. According to the value range and meaning of X, it shows that when x = 5, Y > 5, and x = 3, Y8, the latter constant holds
If a = 2, y = - 7
If A5, x = 5, Y8

If a-3a = - 3, then the value of algebraic formula 5-a + 3b is? In the function y = root 2X-4, the value range of independent variable x is?

A-3a = - 3, then the value of the algebraic formula 5-a + 3b is the value without B
a=1.5,5-a+3b=3.5+3b
In the function y = root 2X-4, the value range of the independent variable x is?
That is, 2X-4 ≥ 0, X ≥ 2

Given the function f (x) = {X & sup2; + 4x, X ≥ 0,4x-x & sup2;, x < 0, if f (2-A & sup2;) > F (a), then the value range of real number a

F increases monotonically, 2-A & sup2; > A, - 2 < a < 1
