Hi there! We are given three functions below:

[tex] \large \boxed{f(x) = \frac{2 + {x}^{2} }{x + 6}} \\ \large \boxed{g(x) = \sqrt{1 + 7x} } \\ \large \boxed{h(x) = | \frac{3}{4} x - 14 | }[/tex]

Next, we are going to substitute the values that replace x-term. Substitute these values in each functions.

We are given below:

  • f(4)
  • g(2)
  • h(8)

Therefore,

[tex] \large{f(4) = \frac{2 + {4}^{2} }{4 + 6} } \\ \large{g(2) = \sqrt{1 + 7(2)} } \\ \large{h(8) = | \frac{3}{4} (8) - 14}| [/tex]

Then evaluate the value.

[tex] \large{f(4) = \frac{2 + 16}{10} } \\ \large{g(2) = \sqrt{1 + 14} } \\ \large{h(8) = | 3(2) - 14}| [/tex]

[tex] \large{f(4) = \frac{18}{10} \longrightarrow \frac{9}{5} } \\ \large{g(2) = \sqrt{15} } \\ \large{h(8) = | 6- 14| \longrightarrow | - 8| = 8 }[/tex]

Answer

  • f(4) = 9/5
  • g(2) = sqrt(15)
  • h(8) = 8
