The vertex of a quadratic function is located at (1, 4), and the y-intercept of the function is (0, 1). what is the value of a if the function is written in the form y = a(x – h)2 + k? a=

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
