Mathematics
1 answer:
Kaylis [27]3 years ago

Answer:

{12,15}

Step-by-step explanation:

Given the function f(x) = x+5, if the range of the function is {7,9}, the domain of the function is derived by simply finding the value of the function at each end point.

At endpoint x = 7,

f(7) = 7+5

f(7) = 12

At endpoint x = 9

f(9) = 9+5

f(9) = 14.

The function domain is therefore at {12,14}

How do i do this, my son is struggling and he needs help
expeople1 [14]

Answer:

32

Step-by-step explanation:

angle a is the outside angle. It creates a circle that will always equal 360 degrees. Since the outside angle is 302, the inside angle must be 58 degrees (360-302). The top square angle will be 90 degrees (a square angle is always 90 degrees). Since the angles in a triangle always add up to 180 degrees, we need to add 58 and 90, and then subtract it from 180, which equals 32. So, angle x equals 32.

kondaur [170]
F(x) = 4x
so f(-2) = 4*-2 = -8  
and 
g((f(-2)) = g(-8) =  -16-1 = -17
