A.x = 10
B. x = 9
C.x = 11
D.x = 8
You can find the value of x in the function f(x) = 3x - 7 when f(x) = 20 by isolating x in the equation. This process leads to an answer of x = 9.
To solve this problem, you need to substitute the given function's value f(x)=20 into the equation and solve for x.
So, you have the equation 3x-7=20. In the next step, you add 7 to both sides to isolate 3x on one side, which gives you 3x=27.
Finally, divide both sides by 3 to find the value of x. Doing so, you get x = 27/3, which simplifies to x = 9.
Therefore, when f(x) = 20, the value of x is 9, which matches answer option B.
