Answer:
Hence, option B) is true.
Step-by-step explanation:
Given
g(t) = t² - 2
h(t) = t + 4
To determine
Using the formula
In order to determine g(h(-4)), first we need to determine h(-4), so
substituting t = -4 in h(t) = t + 4
h(t) = t + 4
h(-4) = -4 + 4
h(-4) = 0
so we can write
now, to determine g(0), substitute t = 0 in g(t) = t² - 2v
g(t) = t² - 2
g(0) = (0)² - 2
g(0) = 0 - 2
g(0) = -2
so, finally we get
Therefore,
Hence, option B) is true.
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = ( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ = ( take the cube root of both sides )
x =
Change y back into terms of x, then
(x) = = → A
