The function g is given by g(x)=−2(x+2)−6. which of the following expresses the value of g(b−5)?

D. -2b

Step-by-step explanation:

g(x)=−2(x+2)−6

given that x = b-5  ---> substitute this into the equation

g(b-5) = −2((b-5)+2)−6

= −2(b-5+2)−6

= −2(b-3)−6

= −2b-3(-2)−6

= −2b+6−6

= -2b

y= -2x+4, have a great day
