WebFree functions calculator - explore function domain, range, intercepts, extreme points and asymptotes step-by-step WebAssuming that 𝑔 is a linear polynomial function in 𝑥. Then we have: 𝑔 (𝑥 + 6) = 5𝑥 + 8 The variable we use doesn't matter, so to avoid confusion, we will write this functional equation in 𝑘 instead of 𝑥: 𝑔 (𝑘 + 6) = 5𝑘 + 8 Since 𝑘 ∈ ℝ, we let 𝑘 = 𝑥 – 6 where 𝑥 ∈ ℝ. Thus: 𝑔 (𝑥 – 6 + 6) = 5 (𝑥 – 6) + 8 Which we reduce to: 𝑔 (𝑥) = 5𝑥 – 22

WebMar 3, 2024 · There are 3 steps to finding an inverse: 1) change notation f (x) = to y =. So, y = 2x + 7. 2) Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x. So, x = 2y + 7. 3) Since x is the dependent variable and y is the independent variable and it is always a zillion times easier to solve a problem in y ...
