Question

Evaluate f(x) = 4x+5 for x = 1.

Answer 1

Here, f(x) = 4x + 5

So, f(1) = 4(1) + 5

f(1) = 4 + 5 = 9

In short, Your Answer would be: 9

Hope this helps!

Answer 2

For
`\(f(x) = 4x + 5\)`, when x = 1, the function evaluates to 9.

To evaluate the function
`\(f(x) = 4x + 5\) at \(x = 1\)`, substitute x with 1 in the expression. This yields:

`\[f(1) = 4 * 1 + 5 = 4 + 5 = 9.\]`

So, when x is equal to 1, the function f(x) equals 9. In the context of the function, this means that if you input 1 into the expression 4x + 5, the output or the value of the function is 9.

The function f(x) = 4x + 5 represents a linear relationship where the coefficient of x is 4, indicating that for each unit increase in x, the output of the function increases by 4. The constant term 5 is the y-intercept, the value of the function when x = 0.
