multiple-choice question
what type of function is this?
exponential
quadratic
linear
rewatch
$y = x + 1$
input $x$: -3, -2, -1, 0, 1, 2, 3
output $y$: -2, -1, 0, 1, 2, 3, 4
coordinate plane (with a graph of points on the coordinate grid)

Explanation:

The function given is \( y = x + 1 \), which is in the form of \( y = mx + b \) (where \( m = 1 \) and \( b = 1 \)), the standard form of a linear function. Also, the graph (points plotted) and the table of values show a constant rate of change (slope), which is a characteristic of linear functions. Exponential functions have a variable in the exponent, and quadratic functions are of the form \( y = ax^2+bx + c \) (with \( a
eq0 \)), so this function is not exponential or quadratic.

Answer:

Linear (the option with "Linear" text should be selected, e.g., if the options are A. Exponential, B. Quadratic, C. Linear, then the answer is C. Linear)
