Question

If g(x) = 1-2x, find each value.

Find g (-12)

Find g (0)

Find -5 g (4) - 1

Answer 1

25 , 1 , 34

Explanation:

substitute x = - 12 into g(x)

g(- 12) = 1 - 2(- 12) = 1 + 24 = 25

substitute x = 0 into g(x)

g(0) = 1 - 2(0) = 1 - 0 = 1

substitute x = 4 into g(x)

- 5(1 - 2(4)) - 1 = - 5(1 - 8) - 1 = - 5(- 7) - 1 = 35 - 1 = 34
