Answer:
(1) -5
Step-by-step explanation:
Put the value where the variable is, read the graph, and do the arithmetic.
g(2) = 3f(2) -2 = 3(-1) -2
<em> g(2) = -5</em>

<em>Additional comment</em>
f(2) is the point on the graph where it is 2 units to the right of the y-axis. At that point, the graph is 1 unit below the x-axis, so f(2) = -1.

Answer: a. x=4 b. x=17.5
Step-by-step explanation:
a. 5x/2+1=11
subtract 1 from both sides : 5x/2=10
multiply both sides by 2 : 5x=20
divide both sides by 4 : x=4
b. 2x/7-3=2
add 3 to both sides : 2x/7=5
multiply both sides by 7 : 2x=35
divide both sides by 2 : x=17.5
