If f(x) = 2x – 1 and g(x) = x2 – 3x - 2, find (f + g)(x).
o
a. (f+ g)(x) = -x-3

b. (f + g)(x) = x2 - x - 3

c. (+ g)(x) = x + 5x + 3

d. (f+ g)(x) = x-3
15

Option B

Step-by-step explanation:

In this problem we have the function

and the function

They ask us to perform the operation:

Therefore we must perform the algebaic summa of the function f plus the function g

Now we siplify the expression

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
