Question
Find the domain and range of each function. Write the answer using interval notation.$$f(x)=-2(x+4)^{2}+15$$
Step 1
The vertex form of a parabola is given by $f(x) = a(x-h)^2 + k$, where $(h, k)$ is the vertex of the parabola. Comparing this with the given function $f(x) = -2(x+4)^2 + 15$, we can see that the vertex of the parabola is $(-4, 15)$. Show more…
