Question

F(x)=-4x+7;f(1) Evaluate

Answer 1

f(1)= -4(1)+7
f(1)= -4+7
f(1)= 3

Answer 2

The answer is 3

Explanation:

`f(x)=-4x+7`

To find f(1) , substitute the value of x that's 1 into f(x), that is for every x in f (x) replace it with 1

We have

`f(1) = - 4(1) + 7 \\ = - 4 + 7 \\ = 3 \: \: \: \: \: \: \: \: \: \: \:`

We have the final answer as

`f(1) = 3`
