If f(x)=4x-1 and g(x)=x^2+7 ,find G(f(x))
frutty [35]

Answer:

g(f(x))=(4x-1)^2+7=16\,x^2-8x+8

Step-by-step explanation:

Given:

f(x)=4x-1\\and \\g(x)=x^2+7

Then the composition of functions:

g(f(x))=g(4x-1)=(4x-1)^2+7= (16\,x^2-8x+1)+7=16\,x^2-8x+8

where we have written the final functional expression in its standard form.

X^2-7x-34=10<br><br> Please help me answer this question thank you
elena-s [515]

Answer: x = 4,11

Step-by-step explanation:

x^2 - 7x - 34 - 10 = 0

x^2 - 7x - 44 = 0

Factorise it

x^2 - 11x - 4x - 44 = 0

x ( x - 11 ) - 4 ( x - 11 ) = 0

(x-4)(x-11) = 0

x = 4,11

Standard normal curve between z=.42 and z=1.92<br> a= .6902<br> b= .3098<br> c= .1902<br> d= .8098
soldier1979 [14.2K]
The correct answer is Choice B: 0.3098.

To find the answer, you have to use a normal distribution table. Look up the percents for each z-score and subtract them to find the region between.

z = 1.92 the percent is 0.9726

z = 0.42 the percent is 0.6628

0.9726 - 0.6628 = 0.3098
