Answer:

f(-2) = 65

Step-by-step explanation:

What f(-2) means is that -2 will be substituted for the value of x, which will result in an output.

f(x) = 6(8-x) + 5

f(-2) = 6(8-(-2)) + 5

f(-2) = 6(8+2) + 5

f(-2) = 6(10) + 5

f(-2) = 60 + 5

f(-2) = 65

Therefore, when x=-2, y=65, which essentially means f(-2) = 65
a) the notion f(-2) means that x is (-2)
However f(x) is another way of saying y

b) f(-2)= 6(8 -(-2))+5
F(-2)= 6(8+2)+5
F(-2)=6(10)+5
F(-2)=60+5
F(-2)=65
