Question

If g(x) = 3(x − 2), find the value of x if g(x) = 6.
12
2.6
8
4

Answer 1

The answer is 4

Answer 2

substitute 6 for x what do you get?

Answer 3

instead of g(x) substitute 6

Answer 4

If g(x) = x2 + 3, find g(4).
11
19
16
8

Answer 5

6=3(x-2)

Answer 6

expand the right side
Then add both side by 6
Lastly divide both sides by 3

Answer 7

For the second question:
Substitute 4 for any of the x values.
(4)2+3
Multiply 4 and 2
8+3
Finally add to get 11

Answer 8

For the function f(x) = x + 5, what is the ordered pair for the point on the graph when x = 4w?
(4w, x + 5)
(4w, 4w + 5)
(x, x + 5)
(x, 4w + 5)

Answer 9

The question gives you the x coordinate so now all you have to do is find the y coordinate.
X=4w
Substitute the x value into the equation to get the y coordinate.
F(x)=4w+5
F(x) can be replaced by y.
Y=4w+5
Final answer would be (4w,4w+5)

Answer 10

Let f(p) be the average number of days a house stays on the market before being sold for price p in $1,000s. Which statement best describes the meaning of f(150)?
This is the average number of days the house stayed on the market before being sold for $150,000.
