with increasing the value of x , value of expression
decreases continuously .
Explanation:
Here we have , an expression as 100-x or ,
. We need to tell what happens to the value of expression when value of x increases :
According to question ,Given expression is in form of f(x) = mx +c ,value of slope & y-intercept is :
![m=-1\\c=100](https://img.qammunity.org/2021/formulas/mathematics/high-school/8od80hk59skm1p9a3bpjfyvwafn0u0i6az.png)
Now , from the graph attached we can see that
For x<100 :
For x=100 :
![f(x)=0](https://img.qammunity.org/2021/formulas/mathematics/high-school/wvi3mxzpky8dxx75wjj4eulze2k1h1l2kh.png)
For x>100 :
![f(x)<0](https://img.qammunity.org/2021/formulas/mathematics/high-school/fyfnvuuyc6109w930573vu2ed5dfluombj.png)
Hence , with increasing the value of x , value of expression
decreases continuously .
