Yes, absjbk29's translation is correct and the one given in this lesson is unequivocally wrong. In most instances Duolingo tends to mark things wrong if you deviate from their expected word order. Here it's not just the word order that I disagree with, it's the literal meaning.
In Victorian times there were big questions of etiquette around who you would introduce first to whom. I guess most Israelis aren't so formal, but we still need correct translations.
You introduce the junior professional to the senior professional: Mr. Ibrahim, I would like to introduce you to Jamal Singh. Similarly, it used to be proper etiquette to introduce the younger person to the older person: Grandma, please meet my neighbors Carlos and Alicia.
I say “used to” because there are many who would argue that it’s fine to ignore this rule, that you’re not being improper if you ignore it.
No, that's not the verb in question. לייצג is pi'el and this is a hif'il skill, so the infinitive of this verb is להציג. Also, the masculine form is different.
pi'el - infinitive - לייצג, masculine sg. מייצג, feminine sg. מייצגת

hif'il - infinitive - להציג, masculine sg. מציג, feminine sg. מציגה

One note. Even though they are from the same root, they don't mean the same thing. לייצג means "present" in the sense of representation, not introduction, as the hif'il verb does.
One of the first things we learned in diplomatic etiquette is that there's a big difference between "I present X to you" and "I present you to X". The higher status person, often the Ambassador or Foreign Minister, is always the receiver of the presentation. An introduction is given to him/her, not vice versa.
