Question

Suppose f(x) =2x-5 and g(x)+= -3x-1

Answer 1

`\sf -17`

Explanation:

Given two functions are ,

`\sf\implies f(x) = 2x - 5 \\\\\sf\implies g(x) = |-3x-1|`

And we need to find out the Value of ,

`\sf\implies f(-1) -g(3)`

• In the given above functions substitute x = -1 and x = 3 respectively , we have ,

`\sf\implies f(-1) - g(3) \\\\\sf\implies 2(-1) - 5 - [ | -3(3) - 1 |] \\\\\sf\implies -2 -5 - | -9-1| \\\\\sf\implies -7 - 10 \\\\\sf\implies \boxed{\pink{\frak\qquad -17 \qquad}}`
