The correct answer is C. Feel free to message me if you need more help, I will reply ASAP!

In this case, the new function is shifted 7 units up from the original. However, since that is one of the choices we can say it is 7 units to the left because x - (-7) based on the general formula y = (x - h) + k. Choice C is the correct answer.

Report 12/04/20 Raymond B. Just graph y=x and y=x+7. the y intercept is 7 higher, showing a shift up by 7. But because it has a slope of 1, it's identical to a shift to the left by 7. Plot a few points, graph them, and you can see they are equivalent, and that's true when the slope = 1Report 12/04/20 Mostafa D. I understand, but in the problem it's f(x+7), the 7 is not being added to the whole equation, just to the X, so it would only be a horizontal change.Report 12/04/20 Raymond B. they're equivalent, a leftward shift of a straight line with any finite nonzero slope is the same as an upward shift. They're equivalent. A leftward shift of y=x by 7 is the same as an upward shift of 7. y=x+7 is equivalent to y-7=x. You can call it manipulating x or manipulating y. But you go with the flow of whatever your instructor or textbook wants. You don't want to confuse some instructors. Although some might be impressed by your observation.Report 12/05/20 Zen F. answered • 12/03/20 Tutor 5 (1)Middle and High School Math Tutor See tutors like this See tutors like this Here is a picture. Always graph the function to get a Big Picture. A picture is worth 1000 words in geometry. How do you know if a graph describes a function?Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.
Which of the following that can test a graph that is function?Definition: VERTICAL LINE TEST
If a vertical line drawn anywhere on the graph of a relation only intersects the graph at one point, then that graph represents a function. If a vertical line can intersect the graph at two or more points, then the graph does not represent a function.
Which graph represents a function answer?To check whether the graph represents a function or not, we perform vertical line test. Vertical Line test: If any vertical line intersects a graph at exactly one point then the graph represents a function otherwise not. Looking into the graphs, the vertical line intersects the graph D at only one point.
