Question

Given that f(x)=2x + 1 and g(x)=3x-1/2x+1
(a) evaluate f(1/2) and g(-1)​

Answer 1

a)

f(1/2) = 2

g(-1) = -3/2

Explanation:

for f(x) = 2x + 1 substitute the x with 1/2

2(1/2) + 1 then solve

1+1

2

for g(x) = 3x - 1/2x + 1 substitute with -1

3(-1) - 1/2(-1) +1 then solve

-3 + 1/2 + 1

-3/2
