What is the value of the expression 8x^2 - 14x + 2 if x = 4

74

Step-by-step explanation:

all about substitution

8(4)^2 - 14(4) + 2

8(16) - 56 + 2

128 - 54 = 74

idk

step-by-step explanation:

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.
