The function f(x) = 3x2 represents the altitude of a blimp, where x is the time in minutes. The function g(x) = −2x − 5 represents the time in minutes, where x is the height in thousands of feet of the blimp. What is the value of f[g(4)]?

the answer is c)8

step-by-step explanaction:

the answer is 99.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
