Let f be the function f(×)= 1/square root of x Let g be the function g(x)=2x²+12

Let h be the function h(x)=7-3x²

(F of g of h) (2)=
(G of h of f) (x)=
Use interval notation and write the domain of (g of h of f)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

so, converting firstly the mixed fractions to improper fractions and then "adding".
