500/92 = 5.43 mol of C7H8
1:1 mol ratio
Mass = mol x Mr = 5.43 x 137 = 743 g (theoretical yield)
Percentage yield = ( actual yield / theoretical yield ) x 100
500/743 x 100 = 67.3% 1dp

Let f(x)=6/5x−1/2. Describe the transformations from the graph of f to the graphs of g(x)=−f(x) and h(x)=f(−x).

aivan3 [116]

Answer:

g(x)=-6/5x+1/2

h(x)=-6/5x-1/2

Step-by-step explanation:

1). g(x)=−f(x) ?

f(x)=6/5x−1/2

g(x)=−(6/5x−1/2)

2). h(x)=f(−x) ?

f(-x)=6/5(-x)−1/2

f(-x)=-6/5x-1/2

h(x)=-6/5x-1/2
