Question

If h(x) = 3x − 1 and j(x) = −2x, find h[j(2)]

Answer 1

what is j(2) equal?

Answer 2

h(j(a)) can be decomposed to:

j(a) = b ; therefore h(b) = h(j(a))

Answer 3

j(2) = #

h(#) = h(j(2))

Answer 4

If h(x) = 3x − 1 and j(x) = −2x, find h[j(2)]
h[ j(x)] = 3 (-2x) - 1 = 6x - 1
-> h[j(2)] = 6 * 2 - 1 = 11
