Hi,For this question, we simply need to plug in x = 4 to the given equation to get:
f(4) = 3(4) + 7
Now, simplify the above computations to get:
f(4) = 12 + 7 = 19 <==== FINAL ANSWER
I hope that helps you out! Please let me know if you have any other questions!

in case you employ the removal technique to clean up the device of equations 3x - 4y = 9 and 2x + 3y = 7, which of here may be the suitable technique? answer #2 technique II: Multiply the two factors of the 1st equation by using 3, and multiply the two factors of the 2nd equation by using 4. Then upload the two equations. this provides a cost of -12y interior the 1st equation and +12y interior the 2nd equation, so including them removes the y variable. the 1st technique might require you to subtract after multiplying so as to get rid of x, so it won't artwork. in case you employ the substitution technique to clean up the device of equations 3x - 2y = 4 and x + y = 5, which of here may be the suitable technique? 3. the two the two of those strategies will artwork.

To find f(4) substitute x=4 in f(x)
f(4)=3(4)+7=19
f(4)=3(4)+7=19

f(x) = 3x + 7 at f(4)
f(4) means value of f(x) when x=4
Hence f(4) = 3×4 + 7 = 19
f(4) means value of f(x) when x=4
Hence f(4) = 3×4 + 7 = 19

f(4) = 3(4) +7
f(4) = 12 + 7
f(4) = 19
f(4) = 12 + 7
f(4) = 19

This is not a question for which we solve anything, it is an evaluation of the function when x = 4. Substitute 4 wherever you see x in the right side and your evaluation yields:
f(4) = 3*4 + 7 = 12 + 7 = 19
f(4) = 3*4 + 7 = 12 + 7 = 19

f(x) = 3x + 7
thus f(4) = 3(4) + 7............since the x was replaced by 4
thus f(4) = 12 + 7 = 19
thus f(4) = 3(4) + 7............since the x was replaced by 4
thus f(4) = 12 + 7 = 19

f(x) is f(4) which means replace "x" as 4 in the equation
f(4) = 3(4) + 7
f(4) = 12 + 7
f(4) = 19
f(4) = 3(4) + 7
f(4) = 12 + 7
f(4) = 19

f(x) = 3x + 7
f(4)=3(4)+7
=12+7
=19 answer//
f(4)=3(4)+7
=12+7
=19 answer//

im pretty sure you just have to substitute the x with 4.
3 times 4 plus 7 equals 19
3 times 4 plus 7 equals 19
