Question

Evaluate =f(×) r 6x-2 for f (2a-3)​

Answer 1

The first option 12a - 20

Answer 2

`\boxed{\sf f(2a - 3) = 12a - 20}`

Explanation:

Function given:

⇒f(x) = 6x - 2

Substitute 2a - 3 into the function in place of x:

⇒f(2a - 3) = 6(2a - 3) - 2

Expand bracket:

⇒f(2a - 3) = 12a - 18 - 2

Add the like terms:

⇒f(2a - 3) = 12a - 20
