Given the function g(x) = 2x + 1. Find the domain using the range.<br> R:{-3, 1}<br> D:{ }
lorasvet [3.4K]

Answer:

D = {-2, 0}

Step-by-step explanation:

If the range is {-3, 1}, that means -3 and 1 are <em>images</em> of some points a, b in the domain. So, there are two points a, b in the domain such that:

g(a) = -3 and g(b) = 1

If g(a) = -3 then 2a + 1 = -3 ------>2a = -4 ------> a = -2

If g(b) = 1 then 2b + 1 = 1 ------> 2b = 0 ------> b = 0

Hence D = {-2, 0}

2# Find the missing variable (s). Round to the nearest tenth.
mel-nik [20]

Answer:

15 cos(33°) m


Step-by-step explanation

Presumably m stands for meters.

If RS were 1, x would be cos(33°)

Multiply sides of triangle by 15 m

When calculating cos(33°) first make sure cos(90°) comes out zero, not -0.448...
