Question

Given ƒ(x) = 14x + 42, find x when ƒ(x) = 35. A) − 12 Eliminate B) −1 C) 1 D) 3

Answer 1

Explanation:

`f(x)=14x+42`

`f(x)=35`

Given the information above, we can simply set up an equation so we can find the value of x.

`14x + 42 = 35`

Subtract 42 on both sides.

`14x=-7`

Divide 14 on both sides.

`x=-(1)/(2)`

So, the value of x is equal to -1/2 when f(x) is 35.
