Question

if f(x)=(x+1)(x-2)/(x-1),then calculate f(7). round answers to two decimal places.

Answer 1

Answer:

f(7) ≈ 6.67

Step-by-step explanation:

To evaluate f(7), substitute x = 7 into f(x) , that is

f(7) = $\frac{(7+1)(7-2)}{7-1}$ = $\frac{8(5)}{6}$ = $\frac{40}{6}$ ≈ 6.67 ( to 2 dec. places )
