Final answer:
To find acceptable values for f(x,y), substitute a number in the range of the function f(x,y) = 9 + √2 + x² + y⁴.
Step-by-step explanation:
To find acceptable values for f(x,y), we need to substitute a number in the range of the function. The function given is f(x,y) = 9 + √2 + x² + y⁴. So, any value that we plug in for both x and y will result in an acceptable value for f(x,y). For example, if we substitute x = 1 and y = 2, we get:
f(1,2) = 9 + √2 + 1² + 2⁴ = 9 + √2 + 1 + 16 = 26 + √2
Therefore, 26 + √2 is an acceptable value for f(x,y).
