Question

The value of k if p(1) for p(y) = 3y⁴ -2y³+15y+k is -1​

Answer 1

Required Answer:-

Given Information:

• p(y) = 3y⁴ - 2y³ + 15y + k
• p(1) = -1

To Find:

• The value of k.

Solution:

It's given that -

→ p(1) = -1

So, put y = 1 in p(y).

→ p(1) = 3 × (1)⁴ - 2 × (1)³ + 15 × (1) + k

→ p(1) = 3 - 2 + 15 + k

→ p(1) = k + 16

Now, we know p(1) = -1,

→ k + 16 = -1

→ k = -1 - 16

→ k = -17

• So, the value of k is -17.

Answer:

• k = -17.
