If f(x) =5x + 12 what is f-1(x)
Olin [163]
To find the inverse of a function, first, let's switch f(x) with y

y=5x + 12

Now, change all the x's into y's and change all the y's into x's

x=5y+12

Now, let's solve this equation in terms of y.

Subtract both sides by 12

x-12 = 5y

Divide both sides by 5

\frac{x}{5} -  \frac{12}{5} =y

Flip the equation so we have the y on the left

y=\frac{x}{5} - \frac{12}{5}

Now, replace the y with f^{-1}(x)

f^{-1}(x)=\frac{x}{5} - \frac{12}{5}

That's your answer. If you need any clarifications, feel free to comment.

Have an awesome day! :)

What type of error is present in the underlined
Aleksandr [31]

Answer:

Type of error: <u>Run-on(comma splice).</u>

Best revision to fix it: <u>Adding a semicolon after beginners </u>.

Explanation:

A run-on sentence is described as a sentence in which two independent clauses are joined inappropriately. It could be either comma splice where the two independent clauses are incorrectly linked using a comma or fused sentence when the two clauses run-on without employing appropriate coordinating conjunction or punctuation marks to separate the two ideas.

In the given sentence, it exemplifies a comma splice type of run-on sentence error. To fix this error, a semicolon after 'beginners' can be employed instead of a comma. This <u>will help in connecting the two ideas appropriately where the first idea leads the second</u>. Thus, the final sentence reads as:

'The guitar is another excellent instrument for beginners; however, it takes more practice than a recorder.'
