X = -b +- sqrt(b^2 -4*a*c)/2a

x = (-10 +- sqrt(10^2 -4*3*-5) )/6

x = (-10 +- sqrt (100 + 60) )/6
x = (-10 +- sqrt (160) )/6
x= (-10 +- 4sqrt10)/6
x = (-5 +- 2sqrt10)/3

x = (1 +- sqrt(1-4*2*6))/4
x= (1+-sqrt(1-48))/4
x = (1 +- sqrt(-47))/4
x = (1 +- i* sqrt(47))/4

x = (-2 +- sqrt(2^2-4*5*5))/10
x = (-2 +- sqrt(4-100))/10
x =(-2+- sqrt (-96))/10
x = (-2 +- 4i sqrt6))/10
x = (-1 +- 2i sqrt6))/5

Someone help! It is urgent!!!
djverab [1.8K]

Answer:

a. f(-1)=12

b. f(2t)=16t²-6t+5

c. f(t-2)=4t²-19t+27

Step-by-step explanation:

For a, b, c, we are given an input. We plug that into f(x) to find our answers.

a.  f(-1)=12

f(-1)=4(-1)²-3(-1)+5

f(-1)=4+3+5

f(-1)=12

-------------------------------------------------------------------------------------------------------------

b. f(2t)=16t²-6t+5

f(2t)=4(2t)²-3(2t)+5

f(2t)=4(4t²)-6t+5

f(2t)=16t²-6t+5

-------------------------------------------------------------------------------------------------------------

c. f(t-2)=4t²-19t+27

f(t-2)=4(t-2)²-3(t-2)+5

f(t-2)=4(t²-4t+4)-3t+6+5

f(t-2)=4t²-16t+16-3t+6+5

f(t-2)=4t²-19t+27

Please help me solve this ;-;
Digiron [165]

Answer:

  C  log3(√((x -4)/x)

Step-by-step explanation:

The applicable rules of logarithms are ...

  log(a/b) = log(a) -log(b)

  log(a^n) = n·log(a)

The base is irrelevant, as long as all logs are to the same base.

__

  \dfrac{1}{2}(\log_3{(x-4)}-\log_3{(x)})=\dfrac{1}{2}\log_3(\dfrac{x-4}{x})=\boxed{\log_3\left(\sqrt{\dfrac{x-4}{x}}\right)}
