F(x) = x² - 81
Finding f⁻¹(x) the inverse function
Let y = f(x) and solve for x.
y = x² - 81
y + 81 = x²
x² = y + 81
x = √(y + 81)
Recall f(x) = y, that means x = f⁻¹(y)
x = √(y + 81)
f⁻¹(y) = √(y + 81)
Therefore f⁻¹(x) = √(x + 81)
Answer:
6
Step-by-step explanation:
f(x)=x^2-5x+6
To find the y intercept, set x=0
f(0) = 0^2 -5(0) +6
f(0) = 6
The y intercept =6
Answer:
About 6 words per second
Step-by-step explanation:
You have to divide 373 words by 60 seconds giving you 6.21666667 which you then have to round down to 6 words per second.
