Question

Evaluate the following expression using the values given.

Find 2x2 - 2z4 + y2 - x2 + z4 if x = -4, y = 3, and z = 2.

Numerical Answers Expected

Answer 1

plug in ur values and write the resulting function out

Answer 2

here is the equation you've been given:
2*x^2 - 2*z^4 + y^2 - x^2 + z^4
every where an 'x' appears, replace it with a -4
x = -4,
every where a 'y' appears, replace it with a 3
y = 3
everywhere a 'z' appears, replaces it with a 2
z = 2

then solve ^_^
