Yes she does, shes also a great teacher for putting in the work for the production if the play.
F(x) = -2/3x + 2.......f(1/2).....this is basically saying x = 1/2..so sub in 1/2 for x
f(1/2) = -2/3(1/2) + 2
f(1/2) = -1/3 + 2
f(1/2) = -1/3 + 6/3
f(1/2) = 5/3 <===
For the first question you best estimate would be : (1, 7) because these points are the closest co-ordinates to the real answer
Second question answer will be: The 2 lines have different slope, one is negative and another is positive. The y-intercepts for both equation are different but the x co-ordinate in both intercepts is 0
Sum of polynomials are always polynomials.
Note that despite it's name, single constants, monomials, binomials, trinomials, and expressions with more than three terms are all polynomials.
For example,
0, π sqrt(2)x, 4x+2, x^2+3x+4, x^2-x^2, x^5+x/ π -1
are all polynomials.
What makes an expression NOT a polynomial?
Expressions that contain non-integer or negative powers of variables, rational functions, infinite series.
For example,
sqrt(x+1), 1/x+4, 1+x+ x^2/2!+x^3/3!+x^4/4!+...., (5x+3)/(6x+7)
are NOT polynomials.
your answer is going to be x 22 and y 34
