Answer:

f(4) = 12

Step-by-step explanation:

Substituting 4 for x in f(x) = 3x, we get f(4) = 3(4) = 12.  We conclude that "the value of the function f(x) = 3x at x = 4 is 12."

what are the coordinates of that center of a circle if the endpoints of its diameter are a(8,-4) and b(-3,2)?
11111nata11111 [884]
You need to add 8 and -3 together to get 5 and divide 5 by 2 to get 2.5
That is the x coordinate
You then need to add 2 and -4 together to get -2 and divide by 2 to get -1
This is the y coordinate
