(f0g) = -2(x+7)+8
(f0g) = -2x-14+8
(f0g) = -2x-6
(f0g)(2) = -2(2)-6 = -4-6 = -10
(f0g)(2) = -10
hope this helps!
Answer:
if m is supposed to be the equals (=) sign then x = 25
Step-by-step explanation:
45 = (2x-5)
+5 +5
50 = (2x)
÷2 ÷2
25 = x
Try it yourself, I'll explain the concept
In a function, each x-value matches to exactly one y-value
If it matches to more than one y-value, it is not considered a function
Now look at the x and y values in each table to determine if it is a function or not
