Practice problem
What value of aaa would make the following linear piecewise function continuous? f(x)={−2x+2−10≤x≤−1227x+a−12<x≤10f(x)=\begin{cases} -2x+2 &-10\le{x}\le{-\frac{1}{2}}\\ \frac{2}{7}x+a &-\frac{1}{2}<x\le{10} \end{cases}f(x)={−2x+272x+a−10≤x≤−21−21<x≤10
a=157a=\frac{15}{7}a=715
a=12a=\frac{1}{2}a=21
a=227a=\frac{22}{7}a=722
a=722a=\frac{7}{22}a=227
Type a concept, like “slope” or “photosynthesis”.
