Answer: 0
<u>Step-by-step explanation:</u>
g(x) = x² + 6x ; x ≥ -3
To find the inverse, swap the x's and y's and solve for "y":
x = y² + 6y
x + 9 = y² + 6y + 9 <em>add 9 to both sides to create a perfect square</em>
x + 9 = (y + 3)²
= y + 3 <em>take square root of both sides</em>
= y ; y ≥ -3
g⁻¹(0) = 
= 
= -3 ± 3
= -3 + 3 , -3 - 3
= 0 , -6
since the restriction is: y ≥ -3, then -6 is not valid
Answer:
Two way ANOVA.
Step-by-step explanation:
The two way analysis of Variance statistical analysis technique is used to analyae and determine the variation in sample means. The two way ANOVA is considered when the independent variable is more Than one. Usually two, in the scenario described, the independent variables in the scenario are ; Socioeconomic Status and Gender.
Also.in Analysis of Variance, the groups or factor level of each independent variable must the atleast 3 or more, this factor level serves as the group of the independent variable. Here the factor levels are High, medium and low, which also means that condition for the number of levels is also met.
