WebGiven the function f (x) as defined above, evaluate the function at the following values: x = −1, x = 3, and x = 1. This function comes in pieces; hence, the name "piecewise" function. When I evaluate it at various x -values, I have to be careful to plug the argument into the correct piece of the function. WebMay 1, 2024 · Evaluate x + 7 when x = 3 x = 12 Solution To evaluate, substitute 3 for x in the expression, and then simplify. When x = 3, the expression x + 7 has a value of 10. To evaluate, substitute 12 for x in the expression, and then simplify. When x = 12, the expression x + 7 has a value of 19.

WebMultiplication and Division happen at the same time, not multiply first, then divide, and the same for addition and subtraction. You don't do all the adding and then do all the subtraction, you do them at once (unless there are brackets/parenthesis of course). So in this case, it is 6 plus -2 plus 9 and you can put those in any order too
