If s(x) = x - 7 and t(x) = 4x2 + 3 which expression is equivalent to (ts)(x)?
Solution:
s(x) = x - 7
t(x) = 4x2 + 3
To find (ts) (x)
(t.s) (x) = (4x2 + 3) (x - 7)
By multiplying both the functions using the distributive property,
(t.s) (x) = 4x3 - 28x2 + 3x - 21
Therefore, (ts)(x) = 4x3 - 28x2 + 3x - 21
If s(x) = x - 7 and t(x) = 4x2 + 3 which expression is equivalent to (ts)(x)?
Summary:
If s(x) = x - 7 and t(x) = 4x3 - 28x2 + 3x - 21
