We can start by first finding the value of 8°F, where F represents the function f(x) = x² - 8.
So, we have:
8°F = 8(f(x)) = 8(x² - 8) = 8x² - 64
Now, substituting x = -3, we get:
8°F(-3) = 8(-3)² - 64 = 8(9) - 64 = 8
Finally, substituting this value into the given expression, we have:
8°F(-3) - 4 = 8 - 4 = 4
Therefore, the statement "True" is correct.
