Answer:
(1,-3)
Step-by-step explanation:
The reason why it would be (1,-3) is because (1,3) is in the first quadrant which is (+,+) and when it is reflected across the x axis, it is then placed into the fourth quadrant which is (+,-). So you need to make the 3 negative and then it will be reflecting across the x axis
Answer:

Step-by-step explanation:
- * - * - = -
6*6*6= 216
Answer:
number 5:

(0-4)+3=-1
Answer:
f(x) = 52
Step-by-step explanation:
f(x) does the same things as y, so when you get your answer, think of it as the value for y when x = - 4
The second thing you should know is that wherever you see an x on the right, you put in - 4
Let x = - 4
y = 2x^2 - 3x + 8
y = 2(-4)^2 - 3(-4) + 8
y = 2*16 - (-12) + 8
y = 32 + 12 + 8
y = 52
Be careful how you hand - 3x when -4 is put in for x. -3(-4) = 12 not - 12
f(-4) = 52
The purpose of finding X is to find what X equals but to do that, you would first need to get X by itself using the proper method rules
