Question #3a09a

↳Redirected from "Suppose that I don't have a formula for #g(x)# but I know that #g(1) = 3# and #g'(x) = sqrt(x^2+15)# for all x. How do I use a linear approximation to estimate #g(0.9)# and #g(1.1)#?"

The error is the verb "are emerging".

Explanation:

The subject of the sentence is "A class" (singular) requiring a verb for a singular subject:
"A class of engineers, called 'knowledge engineers', is emerging to support the experts who are employed as independent consultants."

The verb in the relative clause is correct:
"...who are employed as independent consultants."
The relative pronoun "who" refers to the plural noun "experts".
