Answer: choice A) -4
-----------------------------------------------
Step 1) Draw a vertical line through 1 on the x axis
Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)
Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.
So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.
In short, this is why f(1) = -4
Answer:
X=25
Step-by-step explanation:
This is because X has to be greater than 23. Because you are taking away 35 and the answer is 2, you have to add 23 and 2, and that gives you 25!
Answer:
X^2 + 2(30x) + 900
Step-by-step explanation:
You multiply the sides of each square and add them to get the total of the whole square. For the top left square, you multiply x and x. For the top right, you multiply 30 and x. For the bottom left, you multiply 30 and x as well. And for the bottom right, you multiple 30 and 300. Add these together and you get X^2 + 2(30x) + 900.
