Find the value of x that makes this statement true

Brrunno [24]

$\frac{(-2)^{5x-3}}{(-2)^{2x}} =(-2)^{21}$

$(-2)^{5x-3-2x}=(-2)^{21}$ (The numerator and the denominator has same bases, therefore the powers will get subtracted. It is an exponential property)

$(-2)^{3x-3}=(-2)^{21}$

$3x-3=21$ (As the left hand side is equal to right hand side and the bases are on both the sides are equal too, we will equate their exponential power. Another property)

$x-1=7$

$x=8$ (After simplifying more, you'll get this)

Find the domain and range of the function represented by the graph.

True [87]

Answer:

Step-by-step explanation:

The domain of this function is $[-4,2]$ , as it is shown in the graph that $x$ is only within this interval. The range of this function is $[-4,4]$ , as the smallest value of $y$ is -4 and the largest value of $y$ is 4, and $y$ takes every possible values between them.
