(5) Use a (logically chosen) linear approximation of f(x, y) = p x + y 3 to estimate √ 1.02 + 1.993 . Use a calculator to compute √ 1.02 + 1.993 and compare the result to the approximation. (The approximation better be pretty close to the calculator value!)

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
