s(x) = 2 – x^2 and t(x) = 3x, which value is equivalent to (s of t)(-7)??

Tried distributing -7 to both functions.. Do I multiply them both after? Because I got -1428

amistre64 · Answer

s of t means:  s composed of t.  s(t) = 2-t^2

now the idea is to find t(-7) to determine how to assess s(t) when x=-7

Do I subtract 2-(-7) first or do I multiply first?

amistre64 · Answer

neither,  you determine the value of t, when x=-7
