Evaluate the expression for x = –1.
–48x² − 7x + 27

Evaluate the algebraic expression for the given value or values of the variable(s). 1) y - 7x. 6x + xy. ; x = -2 and y = 3. 1).

Step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
