Question

3. f(x) = x - 4, g(x) = √x
a. f+g
c. fg
f. f/g
b. f-g
​

Answer 1

Answer:

(a). (x + √x) - 4; (b). (x - √x) - 4; (c). x√x - 4√x (f). √x - 4(√x)/x

Step-by-step explanation:

f(x) = x - 4; g(x) = √x

(a). f(x) + g(x) = (x - 4) + √x = (x + √x) - 4

(b). f(x) - g(x) = (x - 4) - √x = (x - √x) - 4

(c). f(x) × g(x) = (x - 4) × √x = x√x - 4√x

(f). f(x) ÷ g(x) = (x - 4) ÷ √x = x / √x - 4 / √x = √x - 4√x / x
