Final answer:
To find the function h(7y - 1), you need to substitute 7y - 1 into the function h(x) = x². Simplify the expression by expanding and combining like terms.
Step-by-step explanation:
To find the function h(7y - 1), we first need to substitute the expression 7y - 1 into the function h(x) = x². This means replacing every x in the function with 7y - 1. So, we have h(7y - 1) = (7y - 1)².
To simplify this expression, we can expand it using the FOIL method. This gives us h(7y - 1) = (7y - 1)(7y - 1) = 49y² - 14y + 1. Therefore, the function h(7y - 1) is 49y² - 14y + 1.
