Answer:
(8, 5, -4, 4)
Step-by-step explanation:
The domain is basically the input or x coordinate. The x coordinates of the points are 8, 5, -4, and 4. Therefore, the domain is 8, 5, -4, and 4.
Answer:
B?
Step-by-step explanation:
X^2 - 20x = 10
x^2 - 20x + 100 = 10 + 100
(x - 10)^2 = 110
Answer:
First box : 100
Second box: 110

Answer:
Step-by-step explanation:
For Question 3, we are simply taking an input for the function, as a value of x and solving the equation. For part a, we substitute 3/14 into the first function, and solve it:
f(x) = 7(3/14) + 2
f(x) = 21/14 + 2
f(x) = 49/14
f(x) = 7/2
For part b, we take the input of -3 into the second function and solve the equation:
h(x) = 4(-3)^2
h(x) = 4(9)
h(x) = 36
For Question 4, we are simply solving this equation by isolating the x variable. First, we simplify the equation to 4-5x+15+2x = -2 and simplify this again to -3x+19 = -2. Now, we can subtract 19 from both sides of the equation to get -3x = -21. Lastly, we isolate the x variable by dividing both sides of this equation by -3, to get x = 7.
