Question

Given f(x)=2x=1.Find f(-3)​

Answer 1

$\huge\boxed{\underline{\mathcal{\red{A}\green{N}\pink{S}\orange{W}\blue{E}\pink{R}}}}$

Given : x=-3

f(x) =2x-1

Now put x=-3 in place of x

f(-3)=2(-3)-1

f(-3)=-1-1

f(-3)=2

f=2+3

f=5

Answer 2

Step-by-step explanation:

Given that value of x = -3

Substitute the value to the given equation

→f(x) = 2x -1

→f(-3) = 2(-3)-1

→f(-3) = -6-1

Therefore

→f(-3) = -7
