given that f(x) = 4x +1 and g(x) = x^2 -2,

which of the following is an expression for f(g(

a. 16x^2 + 8x - 1
b. x^2 + 4x - 1
c. 5x^2 - 1
d. 4x^2 - 7

d.

Step-by-step explanation:

The given functions are

and

We want to find the composition of the f and g.

We substitute into to obtain;

This simplifies to;

Hence the correct choice is d.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
