Evaluate π of two, given that π of π₯ is equal to three π₯ plus seven.
In this question, weβre given the linear function π of π₯ is equal to three π₯ plus seven. In order to evaluate πof two, we need to substitute π₯ equals two into the function. As three π₯ means three multiplied by π₯, we need to multiply three by two and then add seven. This is equal to 13.
If π of π₯ is equal to three π₯ plus seven, then π of two is 13.
