Step-by-step explanation:
4x+7-x=4x-x+7=3x+7
<u>Answer-</u>

<u>Solution-</u>
The given function is,

Now, we have to find the value of f(x) at x=2 i.e f(2), so putting x as 2 in the given function,






Therefore, f(2) was found to be 46.
I believe you answer is c.x2-4 because of its form
It's simple math, but if you don't understand, we can help. To begin with, you must first convert 2 1/4 to an improper fraction. You'd be left with 9/4 after the conversion. Write out 9/4 ÷ 5/8. After doing so, find the reciprocal of 5/8 (switch the numerator and the denominator). Now, write out the question as 9/4 × 8/5. Multiply straight across, as you do not need common denominators when multiplying or dividing fractions. Your final answer should be 72/20. When simplified, you should get 3 2/20, or when simplified to the smallest amount, 3 1/10. Hope I was clear enough to help! :)
