The y-value is 1 less than the square of the x-value. The correct option is D.
What is an expression?
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
The given expression is Y = x²-1, then follow the letters and convert them into numbers we will get:
y-value=y
1 less than=-1
square of x value=x^2
Put the number in order according to the words:
Y = x²-1 ↔ y value is 1 less than the square of x
Therefore, the y-value is 1 less than the square of the x-value. The correct option is D.
