use the function g=f+4 to find the value of g when f=1use the function u=10c to find the value of u when c=5how about this one u
NeTakaya

Given function g=f+4

To find the value of g at f=1

substitute f=1 in the given equation

\begin{gathered} g=f+4 \\ g=1+4 \\ g=5 \end{gathered}

So, at f=1, the value of g will be 5.

(b).

At u=10c

to find the value of u at c=5

substitute the value c=5 in the given equation

\begin{gathered} u=10c \\ u=10\times5 \\ u=50 \end{gathered}

The value of u at c=5 is 50

(c).

Given function u=n-5

to find the value of u at n=7

substitute the value of n=7 in the given equation

\begin{gathered} u=n-5 \\ u=7-5 \\ u=2 \end{gathered}

So the value of u at n=7 is 2

(d).

Given function h=g+13

to find the value of h at g=1

substitute the value g=1 in the given equation

\begin{gathered} h=g+13 \\ h=1+13 \\ h=14 \end{gathered}

The value of h at g=1 is 14

(e).

Given function w=14f

to find the value of w at f=4

substitute the value f=4 in the given equation

\begin{gathered} w=14f \\ w=14\times4 \\ w=56 \end{gathered}

The value of w at f=4 is 56
