Answer:
See below
Explanation:
The first part is asking what you would do if f(x)=2 which means how do you solve for x to make the equation come out to be equal to 2.
2 = 8x + 10 simplifying, 8x = 2 - 10 or 8x = -8 and simplified even further,
x = -1
The second part is asking what the equation would equate to if you replace x with 2. This gives a totally different answer.
? = 8(2) + 10 or ? = 16 + 10 or finally 26
