Answer:
(-1,5) and are points on the graph
Step-by-step explanation:
Given
Required
Determine which point in on the graph
To get which of point A to D is on the graph, we have to plug in their values in the given expression using the format; (x,g(x))
A. (-1,5)
x = -1
Substitute -1 for x in
Convert to index form
Change / to *
This satisfies (-1,5)
<em>Hence, (-1,5) is on the graph</em>
<em></em>
B. (1,0)
x = 1
Substitute 1 for x
<em>(1,0) is not on the graph because g(x) is not equal to 0</em>
C.
x = 3
Substitute 3 for x
Apply law of indices
This satisfies
<em>Hence, </em><em> is on the graph</em>
<em></em>
D.
x = -2
Substitute -2 for x
Convert to index form
Change / to *
This does not satisfy
<em>Hence, </em> <em> is not on the graph</em>
