Answer: First we evaluate g(0), then plug the value into f(x).
g(0) = -2(0) + 7 = 7.
Thus, we need to do f(7).
f(7) = 3(7)-4 = 21 - 4 = 17.

Answer:
The answer is below
Step-by-step explanation:
a) To complete the table of values for y = 3x - 1, we substitute the value of x into the equation and find y.
For x = -2, y = 3(-2) - 1 = -7; For x = -1, y = 3(-1) - 1 = -4
For x = 0, y = 3(0) - 1 = -1; For x = 1, y = 3(1) - 1 = 2
For x = 2, y = 3(2) - 1 = 5; For x = 3, y = 3(3) - 1 = 8
x: -2 -1 0 1 2 3
y: -7 -4 -1 2 5 8
b) The graph is drawn using geogebra online graphing calculator.
c) From the graph, When x = 2.5, y = 6.5
Answer:
A and C
Step-by-step explanation:
Just plug in the point into the equations:
a) 14 = 2(4.5) + 5
14 = 9 + 5 14 = 14 A is correct
b) 14 = 3(4.5) + 1.5
14 = 13.5 + 1.5 14 ≠ 15 B is not correct
c) 14 = 4(4.5) - 4
14 = 18 - 4 14 = 14 C is correct
d) is not correct 12 is already to large and 10 is not a negative so it is far to large
