The graph of f(x)1/2 = (2.5)^x and its reflection across the x-axis, g(x), are shown.

what is the range of g(x)?

The range of g(x) is all real numbers less than 0.

Explanation:

Consider the given function:

The range of a function is the set of all output values.

As it is given that function f(x) reflected across x axis, thus

Now consider the provided graph of g(x):

Here, the set of values that are produced by the function g(x) is lies between -∞ to 0.

Therefore, the range of g(x) is all real numbers less than 0.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
