Answer:
x = 5 only
≡ On a graph, the point touches (5, 0), making <em>x</em> equal to 0.
≡ In other words, you must replace <em>y</em> with <em>0</em> to solve for <em>x. </em>There is no <em>y</em> term in this problem, so you must determine <em>y</em> by separating the coefficients into groups and determining each part.
Step-by-step explanation:
Area= 13.86 cm²
πr²= 13.86 cm²
r= √13.81 ×7/22
r= 2.1 cm
Circumference= 2πr
= 2 × 22 × 2.1 / 7
=13.2 cm
The answer is
f−1(x)=−x/4−2
