Find the indicated values by using the table.<br><br> X= g(x)=2x+1
kaheart [24]
Answer:

g(10) = 21

g(0) = 1

g(10) = 21

g(22) = 45

g(28) = 57

g(16) = 33

Step-by-step explanation:

g(x) = 2x + 1

Then in order to find g(10), replace x over 10

g(10) = 2(10) + 1

g(10) = 20 + 1

g(10) = 21

so g(10) = 21

keep doing this to all of the problems and it should be answered the same way.
