Pls help ASAP

Find f(-2), when f(x) = -0.5x + 12

Let f(-4)=9 Find  a) f-1(9) b)[ f-1(9)]/2 +7

“e” was very happy as he was going to six flags. He pictured the perfectroller coaster and wondered what the equation of such a perfect roller coaster would be. Atsix flags, he discovered the following equation:h(d) = d3-7d2+8d+1where h (d) represents the vertical height above the ground and d represents the horizontal distance the roller coaster has travelled.Using calculus methods only, sketch the function by stating all the following:o Any asymptotes o The y-intercept o The first and second derivative o All critical points and whether they are the maximum, minimum, or neither. o All inflection points and the concavity to the left and right of the points o Graph Show all your work

If f(x) = 3x +2, find the value of: a.) f(0) b.) f(2) c.) f(-1) d.) f(-5) e.) f(-1/3)
