Question

Let f= {(-3,3), (4,8), (2,2), (0,5)}. Find (a) f(2) and (b) f(4).

Answer 1

Answer:

$\begin{gathered} a_)\text{ f\lparen2\rparen = 2} \\ b)\text{ f\lparen4\rparen = 8} \end{gathered}$

Explanation:

Here, we want to find the given values

a) f(2)

This means we have to find the y-value, given that the x-value is 2

From what we have in the set, we can see that f(2) = 2

$f(2)\text{ = 2}$

b) f(4)

We have to find the y-value, given that the x-value is 4

We have this as:

$f(4)\text{ = 8}$
