Evaluate the following function for f(x)=−3 f(x)=2x+5

x = -4

Step-by-step explanation:

Step 1: Write out given

f(x) = -3

f(x) = 2x + 5

Step 2: Substitute f(x)

-3 = 2x + 5

Step 3: Solve for x

-3 - 5 = 2x + 5 - 5

-8 = 2x

-8/2 = 2x/2

-4 = x

Step-by-step explanation:

f(x)=2x+5

To find f(x)=−3 equate f(x) to - 3 and evaluate

That's

2x + 5 = - 3

Subtract 5 from both sides

That's

2x + 5 - 5 = - 3 - 5

2x = - 8

Divide both sides by 2

We have the final answer as
