Question

QUESTION 4 PATTERNS, FUNCTIONS AND ALGEBRA 1. Given 6x³-8x³+2+9x7-4x a. How many terms are there in the polynomial? State the degree of the polynomial c. Determine the value of the polynomial if x=-1 b.​

Answer 1

Answers:

• a) There are 5 terms
• b) Degree = 7
• c) The value is -1

==========================================

Step-by-step explanation:

• a) Each term is separated by a plus or a minus.
• b) The degree is equal to the largest exponent. This applies to single variable polynomials only.
• c) Replace each x with -1. Then use the order of operations PEMDAS to simplify. You should get -1 as the answer. Use a calculator to confirm. It is a coincidence that we have the same input and output. This will not always happen with any general polynomial function.
