Answer 2

Answer:

b = 8

Step-by-step Explanation:

$\huge{\sf{F(x) = \sqrt{x}}$

$\huge{\sf{g(x)=7x+b}}$

$\huge{\sf{y=F(g(x))}}$

$\huge{\sf{y=F(7x+b)}}$

$\huge{\sf{y=\sqrt{7x+b}}$

$\huge{\sf{y^2=7x+b}}$

$\huge{\sf{Putting\: x=4,y=6$

$\huge{\sf{(6)^2= 7×4+b)}}$

$\huge{\sf{36-28=b}}$

$\huge{\sf{8=b}}$
