HELP ME PLEASE!!!! Which scatter plot best represents the function f(x) = 2x + 3? A.scatter plot having y intercept at ordered pair 0, 2 and extreme points at negative 8.6, 1 and 1.6, 7 B.scatter plot having y intercept at ordered pair 0, 4 and extreme points at negative 9.8, 3 and 1.2, C. scatter plot having y intercept at ordered pair 0, 4 and extreme points at negative 8.5, 3 and 2, 7 D.scatter plot having y intercept at ordered pair 0, 2 and extreme points at negative 6.1, 1 and 2.5, 7

    lol i got no idea i always thought \(y=2x+3\) is a line, not a scatter plot it would have \((0,3)\) on the graph which none of these do guess we need to see a picture to figure out which is the best approximation

    Go to desmos.com and plot f(x) = 2x + 3. Then plot each possible set of points from the given choices to see which set gives the best approximation of the line.

    do line of best fit, basically see which one has all of the points clumped together

    can you post a screen shot? it is very hard to read a graph from a bunch of words

    And now we figure out that \(f(x)\) is \(2^x + 3\).

    \[f(0)=2^0+3=1+3=4\] giving the point \((0,4)\) on the graph

    just plug in some low numbers to get the points and see which one matches
