Question

F(x) = -x^3 g(x) = |1/8x-1| what is the value of (g * f )(4)

Answer 1

(g * f )(4)​ = - 32

Step-by-step explanation:

f(x) = -x³

g(x) = |1/8x-1|

(g * f )(4)​ = (g × f )(4)​ = g(4)×f(4)

f(4) = -(4)³ = - 64

g(4) = |1/8(4)-1| = |4/8 - 1| = |1/2 - 1|

g(4) = |-1/2|

Note: absolute value of a negative number gives a positive number

g(4) = 1/2

g(4)×f(4) = 1/2 × -64

g(4)×f(4) = -32

(g * f )(4)​ = - 32
