What is the amplitude of the sinusoidal function? 20 points enter your answer in the box i got -4 but i don't know if that's right.

Simone claims the initial value and y-intercept are the same thing on a graph. is she correct? if you know that a line has a slope of and a y-intercept of 7, what is the equation for that line in slope-intercept form?

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

Write the expression 7x^3-28xy^2 as the product of 3 factors
