1️⃣ -16
2️⃣ 16
3️⃣ 14
4️⃣ -14

Answer 1

Step-by-step explanation:

(-3)

$\\ ( - 3) { }^{2} + 5( - 3) - 10 \\ = 9 - 15 - 10 \\ = 9 - 25 \\ = - 16$

1. option is right.

Answer 2

Question :- If x = -3 then find the value of polynomial x² + 5x - 10.*

1) -16

2) 16

3) 14

4) -14

Solution :-

putting value of x = (-3) in f(x) we get,

→ f(x) = x² + 5x - 10

→ f(-3) = (-3)² + 5 * (-3) - 10

→ f(-3) = 9 - 15 - 10

→ f(-3) = 9 - 25

→ f(-3) = (-16) (option 1) (Ans.)

Hence, at x = (-3) value of f(x) is (-16).
