Question

Solve No.2 and No.3 pls..

Answer 1

the solution of question 2nd is in the attachment.

Answer 2

Step-by-step explanation:

Note: (x, y) = (a, f(a)).

2. In the attachement,

When f(x) = 3, means, for what value of x, f(x) is 3.

Check the table, where f(x){y-cordinate} is 3.

There, satisfying value is 2, as f(2) = 3. So x = 2.

Similarly for g(2), point is (2, g(2)) check the data when x-cordinate is 2.

It is 5. So, g(2) = 5.

3. f(0) asks for the its value when x = 0.

It is 1. Similarly, f(3) = -4.

So, f(0) - f(3) = 1 - (-4) = 5
