Do you see that when we change
f(x) = 7x - 5
to
f(2) = 7(2) - 5
we are simply saying to substitute in 2 for x? Well that is what we are doing:
f(2) = 7(2) - 5
f(2) = 14 - 5
f(2) = 9
Now we find g(4) the same way:
g(x) = 4(x)
g(4) = 4(4)
g(4) = 16
Now we find the difference of the two functions:
f(2) - g(4)
9 - 16
-7
So, the answer is B.
Answer:
-302
Step-by-step explanation:
Answer:
b= -13
Step-by-step explanation:
y=mx+b
-7=3(2)+b
-7=6+b
-7-6=b
-13=b
put it back into y=mx+b
y=3x-13
