Answer:
x-intercepts exist in the 3 functions
y-intercepts exist in the 3 functions
The function h(x) has the lowest minimum.
The function f(x) has the greatest maximum.
Step-by-step explanation:
Given
The attached table
Solving (a): x-intercepts
A function has x intercept if its y value equals 0.
From the table, we have:
<em>All functions have x intercept</em>
Solving (b): y-intercepts
A function has y intercept if its x value equals 0.
From the table, we have:
This applies to all functions in the table;
Hence, all functions have y intercept
Solving (c): Lowest minimum
The minimum of each function is:
The lowest minimum is: h(x) because:
i.e.
Solving (d): Greatest maximum
The maximum of each function is:
The greatest maximum is: f(x) because:
i.e.
