-1*f(-8)-4*g(4) =?

Question

`-1*f(-8)-4*g(4) =?`

Answer 1

-7

Explanation:

From the graph (see attached), we can read off the values of f(-8) and f(4)

when x = -8, y = f(-8) = -5

when x = 4, y = g(4) = 3

hence, substituting the above values into the given equation:

-1 * f(-8) - 4 * g(4)

= -1 * (-5) - 4 * 3

= 5 - 12

= -7
