(1) 12, (2) 5, (3) 13, (4) 30
Step-by-step explanation:
(1) Given expression 2x.
Substitute x = 6 in expression 2x.
⇒ 2 × 6 = 12
(2) Given expression 8 + 3 – x
Substitute x = 6 in expression 8 + 3 – x.
⇒ 8 + 3 – 6 = 11 – 6 = 5
(3) Given expression 6 + 7 – 6 + x
Substitute x = 6 in expression 6 + 7 – 6 + x.
⇒ 6 + 7 – 6 + x = 6 + 7 – 6 + 6 = 13
(4) Given expression 5x
Substitute x = 6 in expression 5x.
⇒ 5× 6 = 30
Answer:
(h.g)(x) = 4x^2 + 5x - 6
Step-by-step explanation:
Given the following: f(a) = x^2 - 8x + 4; g(x) = 4x – 3; and h(x) = x + 2.
(h.g)(x) = (4x – 3)(x + 2)
(h.g)(x) = 4x^2 + 8x - 3x - 6
(h.g)(x) = 4x^2 + 5x - 6
