Is there a difference between 4x and x raised to the power of 4?
Yes. 4x means 4 multiplied by x. x4 means x multiplied by x multiplied by x multiplied by x.
How do you solve the limit as x approaches zero of 1 over x minus 4 plus 1 over x plus 4 all over x?
Limx→0 [ 1 / (x - 4) + 1 / (x + 4) ] / x = Limx→0 1 / (x2 - 4x) + 1 / (x2 + 4x) = Limx→0 (x2 + 4x) / (x4 - 16x2) + (x2 - 4x) / (x4 - 16x2) = Limx→0 (x2 + 4x - 4x + x2) / (x4 - 16x2) = Limx→0 2x2 / (x4 - 16x2) = Limx→0 2 / (x2 - 16) = 2 / (0 - 16) = -1/8
Is y equals x4 an exponetial function?
If the question is, Is y = x4 an exponential function ? then the answer is no.An exponential function is one where the variable appears as an exponent.So, y = 4x is an exponential function.
What is the like term of x x4 4x 4x2 4x4 3x2?
Your question doesn't have raised exponents - don't feel bad, it's not your fault! Your question is probably:What are the like terms among x, x4, 4x, 4x2, 4x4, and 3x2?Like terms have same "letter part" or "variable part". Technically, this is called the literal coefficient.x and 4x are like terms.x4 and 4x4 are like terms.4x2 and 3x2 are like terms.
