Question 1 options:
Musya8 [376]

Answer:

x = 1.56  or x = -2.56

Step-by-step explanation:

From the equation;

x2 +x − 4 = 0

a = 1 , b = 1, and c = -4

x = (-b ± √(b² -4ac))/2a

  = (-1 ± √(1²- 4×1×-4))/2

  = ( -1 ± √(17)/2

  = (-1 ± 4.12)/2

  = (-1 + 4.12)/2 or (-1 - 4.12)/2

  <u>x = 1.56  or x = -2.56</u>

Which graph best represents the function f(x) = 3(1.5)x?
jok3333 [9.3K]

Answer:

B). graph of increasing exponential function going through point (0, 3)

Step-by-step explanation:

Given function is f\left(x\right)=3\left(1.5\right)^x

Now we need to find about which of the given choices best describes the given function. Where given choices are:

A). graph of increasing exponential function going through point 0, 2

B). graph of increasing exponential function going through point 0, 3

C). graph of increasing exponential function going through point 0, 1

D). graph of increasing exponential function going through point 0, 4

plug x=0 into given function

f\left(x\right)=3\left(1.5\right)^x

f\left(0\right)=3\left(1.5\right)^0=3(1)=3

Hence graph passes through point (0,3).

growth factor 1.5 is greater than 1 so that means it is increasing function.

Hence correct choice is:

B). graph of increasing exponential function going through point (0, 3)
