evaluate function

Difficulty understanding the process with functions (see attached)

5) Given the function f describe by f(x)=x+10. Find each of the following: f(0)=

7) Find the indicated outputs for f(x)=5x^2 -3x, f(0)=

8) The function H described by H(x)=2.75x+71.48 can be used to predict the height in centimeters of a women whose humerus is x cm long
Predict the height of a women whose humerus is 37 cm long

9) The function, p(d)=1+ d/33, gives the pressure, in atmospheres (atm), at a depth d in the sea (d is in feet).
Note that P(0)=1 atm, p(33)=2, and so on.
Find the pressure at 50 feet

6) Determine whether the following is a function
Give the function f describe by f(x)=x+19 find each of the following: f(0)=

Please see the attached file for detailed solution.

5) Given the function f describe by f(x)=x+10.

Find each of the following
We know the independent variable x value, so substituting 0 for x to evaluate the function value as:
F(0)= 0 + 10 = 10

7) Find the indicated outputs for f(x)=5x -3x
In place of x, replace it with 0:
F(0)= 5 * 02 - 3 * 0 = ...

Solution Summary

The solution shows how to evaluate the function when the independent variable is given.
