I think the correct answer would be A. cm to days, because to find the unit rate, you have to reduce

If f(x)=log2(x+4), what is f^-1(3)?

Answers

$f\left( x \right) =\log _( 2 ){ \left( x+4 \right) } \n \n \log _( 2 ){ \left( x+4 \right) } =y\n \n { 2 }^( y )=x+4$

$\n \n x={ 2 }^( y )-4\n \n \therefore \quad { f }^( -1 )\left( x \right) ={ 2 }^( x )-4\n \n \therefore \quad { f }^( -1 )\left( 3 \right) ={ 2 }^( 3 )-4=4$

The value of f^-1(3) is 4

What are inverse functions?

The inverse of a function f(x) is the opposite of the function

How to determine the inverse function?

The functionf(x)is given as:

$f(x) = log_2(x + 4)$

Express f(x) as y

$y = log_2(x + 4)$

Swap the positionsof x and y

$x = log_2(y + 4)$

Express as exponents

$2^x = y + 4$

Make y the subject

$y = 2^x - 4$

Express the equationsas an inverse function

$f^(-1)(x) = 2^x - 4$

Substitute 3 for x in the above equation

$f^(-1)(3) = 2^3 - 4$

Evaluate

$f^(-1)(3) = 4$

Hence, the value of f^-1(3) is 4

If f(x) = 2x + 3 and g(x) = (x - 3)/2, what is the value of f[g(-5)]?

Answers

If f(x) = 2x + 3 and g(x) = (x - 3)/2,what is the value of f[g(-5)]?f[g(-5)] means substitute -5 for x in the right side of g(x),simplify, then substitute what you get for x in the rightside of f(x), then simplify.It's a "double substitution".To find f[g(-5)], work it from the inside out.In f[g(-5)], do only the inside part first.In this case the inside part if the red part g(-5)g(-5) means to substitute -5 for x ing(x) = (x - 3)/2So we take out the x's and we haveg( ) = ( - 3)/2Now we put -5's where we took out the x's, and we nowhaveg(-5) = (-5 - 3)/2Then we simplify:g(-5) = (-8)/2g(-5) = -4Now we have the g(-5)]f[g(-5)]means to substitute g(-5) for x inf[x] = 2x + 3So we take out the x's and we havef[ ] = 2[ ] + 3Now we put g(-5)'s where we took out the x's, and wenow havef[g(-5)] = 2[g(-5)] + 3But we have now found that g(-5) = -4, we can putthat in place of the g(-5)'s and we getf[g(-5)] = f[-4]But thenf(-4) means to substitute -4 for x inf(x) = 2x + 3sof(-4) = 2(-4) + 3then we simplifyf(-4) = -8 + 3f(-4) = -5Sof[g(-5)] = f(-4) = -5

Write an equation for the line that is parallel to the given line and passes through the given point. y = x + 8; (2, 16) A. y = x + 14
B. y = x – 6
C. y = x + 6
D. y = x

Answers

y = x + 8...slope here is 1. A parallel line will have the same slope.

y = mx + b
slope(m) = 1
(2,16)...x = 2 and y = 16
now we sub and find b, the y int
16 = 1(2) + b
16 = 2 + b
16 - 2 = b
14 = b

so ur parallel equation is : y = x + 14

The answer is A. y = x + 14
