Step-by-step explanation:
The point (2,80) has the input value x = 2.
Substitute x = 2 into each function.
Answer:
x = ± 1
Step-by-step explanation:
Given
3(x² - 4) + 7 = - 2 ( subtract 7 from both sides )
3(x² - 4) = - 9 ( divide both sides by 3 )
x² - 4 = - 3 ( add 4 to both sides )
x² = 1 ( take the square root of both sides )
x² = ± = ± 1
Thus
x = - 1, x = 1
