Evaluate the function expression
5•f(1)+5•g(9)=

Step-by-step explanation:

By getting our values from the graph,

When x = 1, the blue line has y-value -5.

When x = 9, the dotted line has y-value -6.

Hence,

f(1) + 5 * g(9) = (-5) + 5(-6) = -35.

From the above graph,

→When x=1, y=f(1)=-5

→When x=9, y=g(x)=-6

• 5×f(1)+5×g(9)

=5{f(1)+g(9)}

=5{(-5)+(-6)}

=5(-11)

=-55

part b

it is a function because for every x value there is only one y value
