2 answers:
Answer:
See below ~
Step-by-step explanation:
The function is :
<u>f(x) = x⁴ - 4x² - 5</u>
<u />
=============================================================
Plotting on a graph :
⇒ Once plotted on graph, check where the line of the function intersects the x-axis
⇒ Those will be the zeros of the function
===========================================================
Solution :
⇒ <u>x = -2.236</u>
⇒ <u>x = 2.236</u>
Answer:
A graph shows zeros to be ±3. Factoring those out leaves the quadratic
(x-2)² +1
which has complex roots 2±i.
The function has roots -3, 3, 2-i, 2+i.

Answer:
Call the number we need to find a.
Inequality: (12 + a) ÷ 2 < 27
<=> 12 + a < 54
<=> a < 54 - 12
<=> a < 42
I think it’s b or c mostly b
Answer:
x=ln(61)/ln(4)
Step-by-step explanation:
4^x+3=64
4^x=64-3
4^x=61
x=ln(61)/ln(4)
