Talib is trying to find the inverse of the function to the right. his work appears beneath it. is his work correct? explain your answer.

f(x) = negative 8 x + 4. y = negative 8 x + 4. y minus 4 = negative 8 x. x = (y minus 4) divided by negative 8. f subscript negative 1 baseline (x) = (y minus 4) divided by negative 8.

x = 23.78

step-by-step explanation:

94

step-by-step explanation:

average the numbers and use a variable to figure out the minimum to get a 90.

(79+94+91+92+x)/5=90

x = 94

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)

step-by-step explanation:
