Step-by-step explanation
,the leading term is the term containing the highest power of x. The coefficient of the leading term is called the leading coefficient.
![\begin{gathered} ax^2+bx+c=0 \\ a\text{ is the leading coefficient} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/ggpe169rh48x3i5rjf5yofz9gtiehf3qn2.png)
Step 1
a)
an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.
therefore
![\begin{gathered} graph\text{ A}\Rightarrow open\text{ downward}\Rightarrow negative \\ graphB\operatorname{\Rightarrow}open\text{upwards}\operatorname{\Rightarrow}pos\imaginaryI t\imaginaryI ve \\ graphC\operatorname{\Rightarrow}\text{ open upwards}\Rightarrow positive \\ graphD\operatorname{\Rightarrow}open\text{downward}\operatorname{\Rightarrow}negat\imaginaryI ve \end{gathered}]()
Step 2
b)the leading coefficient "a" indicates how "fat" or how "skinny" the parabola will be.
for
![\begin{gathered} \lvert{leading\text{ coefficent}}\rvert>1,\text{ the parabola will be ''skinny''} \\ \lvert{\text{leadin coefficien}}\rvert<1,\text{ the parabola will be ''fat'', because it grows more slowly} \\ \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/g89fr1c029dt3gb338ifvk76x49zc9itvu.png)
hence, more the skinny the graph is, the more closet to zero
therefore,the coefficient closest to 0 is C
Step 3
c)simiary, the graph with the leading coefficient with the grates value will be
graph B
because the coefficient is greater than zero and this graph is the more "fat"
I hope this helps you
