Answer:
218
Step-by-step explanation:
Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,
f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8
f(3) = 5(8) + 3 = 40 + 3 = 43
f(4) = 5(43) + 3 = 215 + 3 = 218
Answer:
Option 2
Option 4
Option 5
Option 6
Step-by-step explanation:
y is imaginary when the value under the radical is negative
x + 1 < 0
x < -1
2x - 12 < 0
2x < 12
x < 6
6 - x < 0
x > 6
x - 1 < 0
x < 1
1) The given expression 7x^4 + 5x^2 + x - 9 is a polynomial.
2) The given expression 7x^6 - 4x^3 + 1/x is a trinomial.
<u>Step-by-step explanation</u>:
1) 7x^4 + 5x^2 + x - 9
- The number of terms in the above expression is 4.
- An algebraic expression with more than 3 terms is known as polynomial.
- <u>The degree is the power of the x term in a expression</u>
- first term = 7x^4 has a degree of 4.
- second term = 5x^2 has a degree of 2.
- third term = x has a degree of 1.
- fourth term = 9 is a constant term with no degree.
2) 7x^6 - 4x - 1/x
- The number of terms in the above expression is 3.
- An algebraic expression with 3 terms is known as trinomial.
- first term = 7x^6 has a degree of 6.
- second term = 4x has a degree of 1.
- third term = 1/x has a degree of -1.
D there is really no solution unless u get the value of x which I do not have so it can only be simplified into this equation above I hope this is correct and helpful
Would please upload a clear picture
