How do you evaluate the function #f(x) =x^2- 7x + 10# and #g(x)=1-x^2 # for f(0)?

See a solution process below:

Explanation:

Because we are evaluating #f(0)# the function #g(x)# plays no role in this question.

Substitute #color(red)(0)# for each occurrence of #color(red)(x)# in the function #f(x)#:

#f(color(red)(x)) = color(red)(x)^2 - 7color(red)(x) + 10# becomes:

#f(color(red)(0)) = color(red)(0)^2 - (7 * color(red)(0)) + 10#

#f(color(red)(0)) = 0 - 0 + 10#

#f(color(red)(0)) = 10#
