Question

7. If g :x>2x + 1, find:
a) g(2)
b) g(4)
c) g(-1)
d) the value of x if g(x) = 9​

Answer 1

Step-by-step explanation:

a. g(2) = 2x + 1

2(2) + 1

4 + 1 = 5

b. g(4) = 2x + 1

2(4) + 1

8 + 1 = 9

c, g(-1) = 2x + 1

2(-1) + 1

-2 + 1 = -1

d. g(x) > 2x + 9

9 > 2x + 9

9 - 9 > 2x

0 > 2x

Therefore, x = 0/2

= 0
