Question

Evaluate the following expression using the values given: (1 point)

Find 3x2 − y3 − y3 − z if x = 3, y = −2, and z = −5.

Answer 1

Since they give you the values of x y and z you can plug them into the expression and evaluate

(3x^2) - y^3 - y^3 - z becomes

(3*3^2) -(-2)^3 - (-2)^3 - (-5)

Evaluate, being careful about signs and exponents
