Question

For the function G defined by G(x)=5x+3, find G(r+5)

Answer 1

G ( r + 5 ) = 5r + 28

Explanation:

Given ;

G ( x ) = 5x + 3

To Find :-

G ( r + 5 )

Solution :-

plug r + 5 as x in the function.

• G ( r + 5 ) = 5 ( r + 5 ) + 3

distribute 5

• G ( r + 5 ) = 5r + 25 + 3

combine like terms

• G ( r + 5 ) = 5r + 28

Answer 2

Given function:

• g(x) = 5x + 3

Find

• g(r+5)

Substitute x with r = 5:

g(r + 5) = 5(r + 5) + 3 = 5r + 25 + 3 = 5r + 28
