Question

I need help understanding how to format this:

f(x)-4
f(x)=2x+1

an example of another question for it (if you're not sure what im asking), another question was to answer this:

f(4)
f(x)=2x+1
f(4)=2(4)+1

this one is easy to get, but i'm not too sure how to put it on the first one...

Answer 1

Explanation:

To format and solve the equation "f(x) - 4" with the given function "f(x) = 2x + 1," we substitute the function into the equation and solve for x. Here's how it can be done:

f(x) - 4 = 2x + 1 - 4

Simplifying further:

f(x) - 4 = 2x - 3

To answer the question "f(4)" using the function f(x) = 2x + 1, we substitute x = 4 into the function:

f(4) = 2(4) + 1

Simplifying further:

f(4) = 8 + 1

f(4) = 9

Therefore, the value of f(4) is 9 when using the function f(x) = 2x + 1.
