Answer:
The domain is all real numbers.
The function is always decreasing
Step-by-step explanation:
Assuming the given function is

for

Then f(x) is an exponential decay function.
This means that, the domain will be all real numbers.
The range will be y<0
The y-intercept is (0,-1)
There is no x-intercept.
The graph is a decreasing function.
Answer:
Roasted Steak RS=14.47
Grilled Salmon GS= 25.21
Step-by-step explanation:
It's a 2 equation system as follows
E1-> 17RS+14GS=598.95
E2-> 28RS+7GS=581.64
We assume the system has only one solution and apply the following calculation to create a single equation
E3 -> 2x E2 -E1
That way the only incognit will be RS
(28x2 - 17) RS + (7x2 - 14) GS = 581,64x2- 598,95
39RS= 564,33
We solve for RS and then use E1 to solve for GS and E2 to check the answers
17-6 x 10/2+ 12
17-60/2+12
17-30+12
17-18
= -1
<span>2(3 - x) = -16
3 - x = -16/2
3 - x = -8
-x = -8 - 3
-x = - 11
x = 11</span>
