x = 9
Step-by-step explanation:
since the terms are in AP then there is a common difference between consecutive terms, that is
a₂ - a₁ = a₃ - a₂ ( substitute values )
x - 7 = 11 - x ( add x to both sides )
2x - 7 = 11 ( add 7 to both sides )
2x = 18 ( divide both sides by 2 )
x = 9
Shifting a graph up by c units involves adding c to the whole function
therefor
y=ax^2+c is c units higher than y=ax^2 (aka, it is shifted c units up)
