What is f3 for the function (fx)=5x+2 ?

f(3) = 17

Step-by-step explanation:

Step 1. Input the value of 3 into x

This would lead you to get f(3) = 5(3) + 2

Step 2. Multiply your terms

This gets you -> 15 + 2

Step 3. Combine like terms

This gets you f(x) = 15 + 2

Step 4. Answer

17

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
