If g (2x + 5) = 3x + 9 for all real x, then what is g (1)?

Hey!

 

for this 2x+5=1

 

Next, we would get

 

2x=1-5

 

after subtracting we have 

 

2x= -4

 

after dividing by 2 we get

 

x=-2 

 

so we would then plug this in

 

3*(-2)+9

 

After multiplying we get 

 

-6+9

 

after adding we get our answer 

 

3

 

Hope i could help! :)
