HELP PLEASE ITS DUE TMR

Answer 1

`-6`

Explanation:

`-5.f(-2) - 3g(7)`

The values of
`f(-2)` and
`g(7)` have to be read and deduced from the respective
`f(x)` and
`g(x)` graphs

`f(-2)`:

For x =
`-2`, draw a straight vertical line connecting x =
`-2` and the blue
`f(x)` graph. It can be observed that the the blue
`f(x)` graph is touching the x-axis at x =
`-2`. Therefore, the corresponding y [or
`f(x)`] value is 0.

`g(7)`:

For x = 7, draw a straight vertical line connecting x = 7 and the red dashed
`g(x)` graph. Then (from this meeting point) draw a straight horizontal line that touches the y-axis. It can be observed that the corresponding y [or
`g(x)`] value is 2

Now substitute the deduced values in the expression:

`-5.`(0)
`-3.`(2) =
`0 - 6`

=
`-6`
